Hey Gandalfe,
Joplin's "The Strenuous Life"
<Performed> Holst's" First Suite", and "Second Suite"
"Take the A-train" (arrangement for concert band--actually almost any concert band arrangement of big band stuff gives a prominent place to the sax section)
Ross Roy (lovely alto solo)
Shostakovitch "Jazz Suite #2" (Lovely alto solo and alto-tenor duet to open the piece)
Concert band arrangement of "Yakety Sax"
<Performed> Ralph Vaughn Williams" "Sea Songs"
Any of the Mancini medleys
Dragon's arrangement of "America the Beautiful"---a July 4 staple in my part of the world.
And I have always loved the sax part to "Colonel Bogey" (aka theme music from "Bridge over the River Kwai")
