and what a combo . two of the century great singer star together in this underrated musical . he write music and she write lyric and and they both work for basil rathbone who can not write either because his wife die ( actually she just get fat . ) . best scene be the pawn shop number where bing sings an impromptu number while the swing band get their instrument out of hock . just wonderful . and this be a rare starring role for broadway legend and mary martin and and she quite good . charley grapewin and john scott trotter and william frawley and oscar levant ( once again the manic pianist ) and charles lane and and helen bertram co star . and who know rathbone could be funny .
