Anyway, I think I've settled on some working chords for "Someone to Watch Over Me", after some work on Sunday. It's a classic, of course, and though I'm not sure my singing will make it a "keeper", it was worth a try. (Not to mention the pure challenge of getting it working.)
And we were at Daleen's mom's house last night, and she had a "Songs of Irving Berlin" book on the piano, from which I plucked "Putting On the Ritz". Surprisingly, the chords work quite well on guitar (unlike, for instance, "End of the Innocence", as discovered on Saturday). Again, I don't know what the vocal will sound like yet, but there's a small chance it'll work out. (It probably falls under the category of "Songs to Stump the Lead Player", but it might be fun.)
I guess I've discovered that some songs that sound OK in the bedroom, fall flat at Tully's -- and vice versa. So I'm stuck with working them up anyway, and trying them out live.
P.S. In reading various sites on Berlin, one claimed he only played didn't read or write music, never learned to play properly, and only played black keys on the piano (!). Using a pitch shifting piano (apparently readily available at the time), he *sounded* in different keys. Another said that he could only play in F#major (which may or may not correspond to "black keys only" -- I guess it's F#major without 4s and 7s). Can that really be true? If so it'd be a amazing collection of pentatonic melodies... I guess I should sit down at the piano and pick out "Ritz", starting on F#.
