Having recently played this – Reed 2 (although listed) does NOT require a piccolo, not scored throughout.
Flute is barely used, though useful to have – I did a rewrite of all flute parts on to clarinet and worked rather well.
Bass Clt, although not written into the part, a low C bass gives lovely depth to some songs.

Edited to remove piccolo from reed 2. Thanks–
