Ira and George Gershwin.

"George and Ira were the two remarkable music masters of the time. Actually, I became quite friendly with both of them. I'd visit their home on the Upper West Side and listen to George play. George was an incorrigible entertainer. If there was a piano around, you couldn't keep him away from it. Ira was the exact opposite of George, very much introverted, very shy. Ira authored 'I'm bidin' my time, that's the kind a guy I'm.' He never boasted about his abilities as a lyricist. Of course, he didn't need to." HOL/195
