March 29 was Piano Day (because it was the 88th day of the year and pianos have 88 keys), so I listened to Rod Argent's
Classically Speaking. I was finally able to confirm something I've been suspicious of for a long time. I'd thought that the section of "Be Glad" starting at ~3:31 was a quotation (or near quotation) of a classical piece, but I hadn't been able to place it. It turns out that the piece I was looking for is on
Classically Speaking. At ~3:12 in the Prelude in C# minor, Op. 45, No. 1 by Chopin, Argent starts playing this:
I don't know if what he plays in "Be Glad" is exactly the same (for one thing, it sounds quite a bit lower), but I think it's a similar sort of figure.
