(Title a la Dorothy Zbornak)
I was busking at Porter, playing "Sunrise, Sunset", when a guy came up and told me...not asked me, told me...to play something happier. So I switched to "To Life", which wasn't happy enough for him. I think I then switched to "Devil's Dream", at which point he said something like, "See? People like HAPPY music!"
If all I played was fast fiddle tunes, both I and my audience would probably get bored. Interest lies in contrast. And I like Fiddler on the Roof, even if it's not "happy" enough for this guy. Hmph.
