"The Entertainer" is a 1902 classic piano rag written
by Scott Joplin. One of the classics of ragtime, it
returned to top international prominence as part of the
ragtime revival in the 1970s, when it was used as the
theme music for the 1973 Oscar-winning film The Sting.

Thank you, I'm enjoying playing it. There is a typo bar 26 with # missing from G in sax part. I find it sounds truer to original to play pt 2 (bars 21-30.5) mostly up an 8ve, and that's easily within range.
