Hi, Baboon. Good taste! I like this Glen Miller tune and gave it a listen. I then went to YT and listened to Blue Moon by Glen Miller, another great tune. Check out the Al Bowlly version (1935). It’s in Eb Concert which is F on the tenor and C on the alto. I play the Al Bowlly version; it’s a bit more uptempo and has more of a swing to it than the GM version, imo. Al Bowlly was the guitar player in the band in his early days and would have tuned his guitar down a half step to play it in E. Eb is not a favored key for guitar players. Like Glen Miller, Al Bowlly died in World War II. He was killed in the London Blitz in 1941. Needless to say, I’m a huge Al Bowlly fan. He was huge in the late 20s, 30s and up until his death.
