There's a piano version of Song and Dance, at least:

I too am a fan of Dale Underwood. Not only does he play altissimo like it was built into the horn, he also plays it mellow as can be.
I tried to order Soliloquy and Song and Dance AGES ago from a place called Onondaga Music here in New York (state, that is

). I placed the order, and they said they'd have to special order it...so I was like "Ok, go ahead and do that...that's fine." I actually forgot I had ordered it after quite a while because I never got it...so about a year later, I remembered...was pretty P-O'd...and called them back--"Yeah about a year ago, I placed an order...kinda wondering how long it takes to deliver...etc..." So about another half year went by with no avail...and I got a letter in the mail from them saying that they were going out of business...and were unable to fulfill my order... grr..anyway enough ranting.
But yeah, anyone know if the band arrangements of some of his stuff are available?
