This is a loose transcription of the famous Louis Armstrong recording. It includes
the opening cadenza and the solo he plays at the end. Trombone gets a chorus of blues
and the French horn gets to carry the melody for a chorus as well (don't worry, the horn
doesn't have to swing!). This is more of a "chamber jazz" type piece than the other
New Orleans-style arrangements posted. Your trumpet 1 should really check out the
original Armstrong recording to make this sound authentic. Search "Louis Armstrong
West End Blues" to find some YouTube audio & video postings.
