Here's a great medium tempo swing chart that opens with a sax soli followed by the trombones with a big unison statement.  The solos in this one are for any player and suggested solos are included as well as changes for improvisation.  A solid shout chorus follows the solo section in this tune that swings all the way home!  Your "little cats" will sound like "big cats" with this exceptional chart at the easy grade level!  Very highly recommended!
