It's been over 30 years since I played the drum in the New Ashmolean Marching Society And Student Conservatory Band in a production of Where's Charlie, but here's my best shot at the lyrics:

Though they march only slightly out of tempo
Though they play only slightly out of tune
Though there's just a suggestion in the oboe
Of the sound of a hound beneath the moon
Though the trumpet's a little independent
And the drummer is not exactly choice
Still, the old college spirit is upon me
And I shout every time at the top of my voice
For the New Ashmolean
Marching Society
And Student Conservatory Band
Yes, the New Ashmolean
Could have beat Napoleon
With all those deadly instruments at hand
There are those who favor the philharmonic flavor
But to me the finest in the land
Is the New Ashmolean
Marching Society
And Student Conservatory Band

Yes, the New Ashmolean
Marching Society
And Student Conservatory Band
If you're analytical
Sensitive or critical
You'll like it more the farther back you stand
But to me, it's bully, it satisfies me fully
Just to hear those trumpets close at hand
Of the New Ashmolean
Marching Society
And Student Conservatory Band
