Yes, it was nicely played, but a little creativity with instrumentation or modulations would add a lot to his playing.

I perform that tune, when requested and I usually use a sax solo through the first time, then I go to the sax/clarinet combo, then a solo trumpet in the little middle section, then back to the sax/clarinet combo.

I go through it a 3rd time, with piano and strings for the main section but feature a clarinet on the middle section, then finish with the piano/string thing.

I also modulate as I go into the 3rd time through, which really lifts it, IMO...

If I sing it, I use a different arrangement with a variation of
the above stuff...
