"Marry Me a Little" is a fantastic song. I, in fact, find it superior to "Being Alive". John Barrowman's rendetion of "Marry Me a Little" in 'Putting It Together' is superb.
As for the 'other' version of 'Being Alive', you're thinking of Larry Kert. Dean Jones, who originated the role of Bobby, struck a deal with Hal Prince that he would give it his all for the recording, opening night and a few performances after that, then quitely leave due to maritial problems of his own. Larry Kert assumed the role, and was the only replacement in history to get the Tony nomination. Halpprince decided to record Larry Kert's version of 'Being Alive', also. I find both versions equally enjoyable.
NOTE: Larry Kert also originated the role of Tony in 'West Side Story'
