A lot of these are covers. “Whole Lotta Love” was stolen from Willie Dixon; he sued their white boy asses and won. “Big Ten Inch” was written by Bull Moose Jackson, and credited by Aerosmith as the writer.
There is one Budgie song that has a salacious line/title that it took me embarrassingly long to grasp,
____You’re the biggest thing since powdered milk, baby you know it’s true
I don’t get it.
“Mama’s got a squeeze box, Daddy doesn’t sleep at night.”
No one’s mentioned this one yet. Huh.
It helps to have a stronger response to the convexities than I do.
He couldn’t sleep because she wouldn’t stop playing that damn accordian. 
“Chestnut Mare” by the Byrds
Really? I’ve always thought that it was really a literal song about catching a horse. Bob Dylan’s New Pony on the other hand is pure sexual Blues innuendo, with some original phrases nonetheless:
I got a new pony, she knows how to fox-trot, lope and pace
Well, I got a new pony, she knows how to fox-trot, lope and pace
She got great big hind legs
And long black shaggy hair hanging in her face
[…]
Come over here pony, I, I want to climb up one time on you
Come over here pony, I, I want to climb up one time on you
Well, you’re so bad and nasty
But I love you, yes I do
“It goes in,and out, and in, and out, and in, and out,
playing all night, and the music’s all right,
Momma’s got a squeezebox, Daddy never sleeps at night!”
Sheena Easton invited someone to “come spend the night inside my sugar walls”. The video implied that she was talking about her apartment. I don’t think so.
Sir Mix-A-Lot “Baby Got Back”:
“My anaconda don’t want none,
Unless you got buns, hon!”
The film was based on a stage musical, which, in its original form, was apparently substantially raunchier than the toned-down (but still naughty) movie version.
Keep on Churnin’– Wynonie Harris
‘Course she keeps him up, she doesn’t even know how to play it.
A few more by The Who:
I’m dreaming from the waist on down
I’m dreaming but I feel tired and bound
I’m dreaming of a day when a cold shower helps my health
I’m dreaming… dreaming - of the day I can control myself
Pictures of Lily made my life so wonderful
Pictures of Lily helped me sleep at night
Pictures of Lily solved my childhood problems
Pictures of Lily helped me feel alright
I kissed a few and once did sit
On Ivor the Engine Driver’s lap
And later with him, had a nap
“Give you my dull surprise”
Bob Seger’s “Night Moves”
Speaking of Seger,
They do respect her butt
They love to watch her strut
My cousin said, no, no, no, it’s “but”, it says so right in the lyrics on the sleeve; I said listen to the damn song, he listened and conceded, yeah, it’s “butt”.
My son’s School of Rock band played this song. A bunch of 12-13 year olds.
I thought it was a questionable song choice. Of course, I just laughed since they didn’t really understand what they were singing.
There’s this Canadian dude named David Wilcox, with a song called “Laying Pipe.”
It’s a pretty good tune! You can google the lyrics.
Steve Miller Band, “The Joker”
Really love your peaches
Wanna shake your trees
From Prince’s “Little Red Corvette”:
I guess I must be dumb
'Cause you had a pocket full of horses
Trojan and some of them used
Ew.
And then:
I guess I should have closed my eyes
When you drove me to the place
Where your horses run free
'Cause I felt a little ill
When I saw all the pictures
Of the jockeys that were there before me
Kind of a mixed metaphor there, as horses running free would tend not to have jockeys. Still, we get that she’s not actually running a horse stable.
That whole song, really.
