Bzzzzzt! It was mentioned in post #14 and Cat Stevens wasn’t the artist. That would be Harry Chapin.
Tower of Song by Leonard Cohen
“Well my friends are gone and my hair is grey
I ache in the places where I used to play”
For a more optimistic take, there’s Have a Good Time by Paul Simon:
Yesterday it was my birthday
I hung one more year on the line
I should be depressed
My lifes a mess
But Im having a good time
Paul Gross, Ride Forever. from the soundtrack of the series Due South. I love that song.
Bouncing Souls, '87
Do you remember when the days gone by
or is there no point for us to even try
Back when we didn’t have a care in the world,
Getting drunk and chasing girls
Do you remember the days gone past and how we
always wanted the good times to last
Fleming & John, The Way We Are
Can we still have adventures,
When we’re old and wear dentures?
Will you kiss me on the lips?
Do you think we’ll dance with our plastic hips?
And when you look at me,
Will you see the girl you met when you were nineteen?
Will you see a lady with a limber heart,
Swimming in the water with the sharks?
Dido, See You When You’re 40
So see you when you’re forty,
Lost and all alone,
Being comforted by strangers,
you’ll never need to know,
Not sad because you lost me,
But sad because you thought it was cool,
To be sad.
Madonna, This Used to be My Playground
This used to be my playground
This used to be my childhood dream
This used to be the place I ran to
Whenever I was in need
Of a friend
Why did it have to end?
Aimee Mann, Ghost World
Finals blew, I barely knew
my graduation speech
and with college out of reach
if I can’t find a job I’m left with Dad and Myrtle Beach
So, I’m bailing this town–or
tearing it down–or
probably more like hanging around
10,000 Maniacs, These Are Days
These are days you’ll remember.
Never before and never since, I promise,
Will the whole world be warm as this.
And as you feel it, you’ll know it’s true
that you are blessed and lucky.
It’s true that you are touched by something
that will grow and bloom in you.
Lee Ann Womack, I Hope You Dance
*I hope you never lose your sense of wonder
You get your fill to eat, but always keep that hunger
May you never take one single breath for granted
God forbid love ever leave you empty handed
I hope you still feel small when you stand beside the ocean
Whenever one door closes I hope one more opens
Promise me that you’ll give faith a fighting chance
And when you get the choice to sit it out or dance,
I hope you dance*
Also, third (fourth?) “Landslide”. Powerful stuff, that song.
NOFX - Theme from a NOFX Album
*We’re professional punkers
We come from the suburbs
After 15 years, we’re still having fun
Now we’re over 30, not looking so purty
At least we got a beat up accordion
That’s Eric our drummer, his father’s a plummer
He drank enough booze to get Rhode Island drunk
Now sober but smelly he’s got one big belly
From livin’ the good life provided by punk
Singin’ singin’ singin’
Buy me a Becks beer or pass me a bong
Gimmie some bushmills I’ll sing you this song
Open another big box of cheap wine
We’re over 30 we’re doing just fine
Hefe’s not satanic he’s one hip Hispanic
He grew up with one dozen cousins and kin
He wears baggy pants he know how to breakdance
You’ve seen him do every impersonation
That’s Melvin on six-string “some tell me I can’t sing”
Oh I think you can just don’t do it 'round me
Stick with what you know playing guitar solo
With Hetson and Watt in punk karaoke
Singin’ singin’ singin’
Buy me a Becks beer or pass me a bong
Gimmie some bushmills I’ll sing you this song
Open another big box of cheap wine
We’re over 30 we’re doing just fine
My name is Fat Mike I’m obsessed with big lesbians
I’ve been a punkrocker for most of my life
I sing kinda flat I’m not really so fat
But that’s how I hit them with a hook or a slice
I’m Kent I do sound “Look he’s getting so round”
Like Timmy The Turtle he counts as he clicks
I’m Jay (I don’t care) someone please cut his hair
I’m Limo from Scotland so gimme haggis
Singin’ singin’ singin’
Buy me a Becks beer or pass me a bong
Gimmie some bushmills I’ll sing you this song
Open another big box of cheap wine
We’re over 30 we’re doing just fine
Buy me a Becks beer or pass me a bong
Gimmie some bushmills I’ll sing you this song
Throw me a qualude, or chop me a line
We’re pushing 40 we’re doing just fine
Buy me a castle or pass me a bong
give me Glenlivet, I’ll sing you this song.
Open another big box of cheap wine,
if you take the low road then I’ll take the high.*
Wow, I was out most of the weekend and am surprised at so many varied responses. Awesome. I can’t believe I didn’t think of some of these.
There’s always the old standby, Try To Remember from the Broadway show The Fantasticks:
*Try to remember the kind of September
When life was slow and oh, so mellow.
Try to remember the kind of September
When grass was green and grain was yellow.
Try to remember the kind of September
When you were a tender and callow fellow.
Try to remember, and if you remember,
Then follow.
Follow, follow, follow, follow, follow,
Follow, follow, follow, follow.
Try to remember when life was so tender
That no one wept except the willow.
Try to remember when life was so tender
That dreams were kept beside your pillow.
Try to remember when life was so tender
That love was an ember about to billow.
Try to remember, and if you remember,
Then follow.
Deep in December, it’s nice to remember,
Although you know the snow will follow.
Deep in December, it’s nice to remember,
Without a hurt the heart is hollow.
Deep in December, it’s nice to remember,
The fire of September that made us mellow.
Deep in December, our hearts should remember
And follow.*
Years May Come, Years May Go by The Irish Rovers.
And Chefguy’s a little late. 
I think it’s called ‘The Doctor’ by Loudon Wainwright.
I went to the Dr -the Dr said ‘Loud, you gotta stop hanging out, with that old In-crowd’
etc
Cant remember which album but someone will be along to tell you soon…
Also ‘Your Dad Did’ by John Hiatt
‘So you go to work just to watch some jerk pick up the perks you were in line to get
The guy that hired you just got fired your jobs expired they just aint told you yet
So you go and buy a brand new set of wheels
Just to show your family just how great you feel
You’re acting like a kid
Just like your dad did’
Great song
