What is that classic rock song that ends with “Oh what a beautiful morning, oh what a beautiful day, oh what a beautiful morning, everything’s going my way?” It’s an up-tempo number, and doesn’t contain those lines until the very end, I think. Help!
That’s not classic rock - it’s a lot older than rock.
I’m trying to remember - was it an old Disney film, or from Showboat?
In my fruitless search for this song I’ve come across a hundred or more variations of the line, including show tunes and all kinds of garbage. But the song I have in mind is definitely a rock song, nothing more and nothing less.
I think that’s the opening musical number from Oklahoma! (Rogers & Hammerstein, I think.)
You are correct, sir! It is the opening musical number from Rodgers and Hammerstein’s Oklahoma. The corn is as high as an elephant’s eye.
But, please note, I have no idea about the answer to the OP. Sorry!
Yes but the Oklahoma number has those words as the opening line, so it’s not what the OP is talking about. Presumably someone included it in some later work. Sampling? Homage. Something like that.
I’m pretty sure those are the last lines of the song as well.
You couldn’t be thinking of the Rascals’ A Beautiful Morning could you?
It’s only real qualification is that is it a rock song, but the the lines the OP quoted are from Oklahoma and that’s about as much rock as Cole Porter is.
Answer to OP: None that I know of, it’s the first line of the chorus.
I reached back in the dark corners of memory for the following.
From the musical “Oklahoma”
Song Title: Oh, What A Beautiful Mornin’ Lyrics
There’s a bright golden haze on the meadow
There’s a bright golden haze on the meadow
The corn is as high as an elephant’s eye,
An’ it looks like it’s climbin’ clear up to the sky.
Oh, what a beautiful mornin’,
Oh, what a beautiful day.
I got a beautiful feelin’
Ev’rything’s goin’ my way.
Somebody may have borrowed it to use as the last line of something or other but it wasn’t from the Broadway Show “Oklahome”
Are you thinking of the cover of “Oh, What A Beautiful Morning” by the Eels? It’s not really classic rock so much as it is modern rock, especially considering that it was released a mere four years ago, but it may be what you remember.
There was a song by either Daniel Boone or D. Boone. The chorus was
oh, oh, oh beautiful Sunday,
oh, oh, oh, beautiful day.
when you say, say, say, say that you love me
this is my, my, my beautiful day
it’s possible it faded out to “oh what a beautiful morning.”

If I’m understanding this question right, there was (and I vaguely remember hearing it) a rock song which concluded with a riff on the Oklahoma show tune – probably by way of irony. This is SOP for a wide variety of songs, from the Loggins “I met my old lover late last night” ending with a brief riff of “Auld Lang Syne” to the Beatles’ insertion of a line from the Marseillaise near the end of “All You Need Is Love.”
So the question becomes, “What rock song – and I think I can narrow it to it being by a late-80s/early-90s hair band – ends with a riff on “O What a Beautiful Morning” from Oklahoma?”
According to [url=http://burnish.net/disc/rockalittle.php]this web page:
Re Loggins “Auld Lang Syne” Polycarp, were you possibly hinking of Dan Fogelberg?
That’ll teach me to go make a sandwich in the middle of a post! 
(My bold) that isn’t Loggins. Its Dan Fogelberg.
Yeah! (In a little known fact – because I just made it up – Dan Fogelburg is an illegitimate brother of Kenny and Dave Loggins! ;))
And another little known fact about the Fogelberg song is that the melody is actually The 1812 Overture, slowed down. : :
Another little known fact is that the 1812 Overture includes a couple of choral sections. There’s a reason that they are not performed very often.
