The Beach Boys' "Good Vibrations: Gold Star 4/9/66" (from The SMiLE Sessions)

Lately I've been listening to The SMiLE Sessions box set.  I listened to the fifth disc this morning, and I noticed that in the second track ("Good Vibrations: Gold Star 4/9/66") at about 1:03 before the next take starts, a guitar plays part of the melody from George Gershwin's "Strike up the Band."  It's the melody to which is sung:

Let the drums roll out
Let the trumpet call
While the people shout
Strike up the band

The final note (for "band") either isn't played or isn't audible (there's some other noise that occurs at the same time that might obscure it), but I was still very excited to hear and recognize this.

Wilson's cited Gershwin as an influence, but I don't know if this quotation is anything more than just coincidence.
