In The Mood - Michael Sweeney, arr. (Grade 2) 

The mp3 is sourced from a Big Band Demo account ( • In The Mood - Demo For... ) - it was a Made for Kids-type video (can't be added to playlists) and didn't have Michael Sweeney in the title, which made it particularly difficult to find. The J.W. Pepper version was cut short and had built-in copyright beeps, and this seems to be pretty darn close to the J.W. Pepper audio, so...
