You'll recognize this tune for sure as a hit by the great jazz pianist Ramsey Lewis. It's a groovy boogaloo chart played at 140 bpm with a lead trumpet range to written G on top of the staff, and written solos are provided for all four trumpets as chosen. The changes are very accessible and will provide an opportunity for some improvisation for developing jazzers.  Optional parts are included for expanded instrumentations. The In Crowd is a fun and happy chart to play. You'll dig it!
