Another 3/4 tune comes to mind . . . JEANNINE I DREAM OF LILAC TIME, 1928, Nathaniel Shilkret, from the film LILAC TIME. I have the sheet music for it and used to play it all the time (in 4/4, as a laid-back jazz piece).
Very melodic . . . but I agree with Al - the audience's age will matter.
BUT, I've found that even with the more esoteric material, most folks like it if it is played well. DAVE
