Some time around 1997 I was working with the Frank Loesser office, and I got to know Colin Romoff, a wonderful arranger and pianist who played rehearsal for a lot of shows. He taught Mary Martin the score for The Sound of Music and played rehearsals for Gypsy. I had lunch with Sid Ramin one day and I mentioned seeing Colin. Sid told me that at Gypsy rehearsals he used to sit at the piano, and a lot of the orchestra licks in Gypsy, like the little woodwind figure in "Wherever We Go" was based on the stuff he would hear Colin making up as he played piano for the singers.
Well, I've never forgotten that advice, and much of the orchestration in every early album I did with BK was based on what he did while the singers rehearsed. At the end of a number, I had a pretty good idea of the feel he wanted and a lot of ideas for the fills. Later, when he was recording tons of things and time was limited, I missed those early rehearsals with the singers and BK singing next to me.
