[Dixielandjazz] Auld Lang Syne -- Best Key for Audience Sing-Along?

[Robert Smith]

Dear Jim,

I must retract my suggestion of C major. I wrote this E-mail at midnight 
when I didn't dare try out the song on the trombone, so i made a right mess 
of trying to find the best key. I've just found a lead sheet published by 
the Norwegian Music Publishing Co. This arrangement is written in the key of 
Eb major, which gives the lowest note as Bb(0) and the highest as C(2)..

Kind Regards

Bob Smith
