Jack O'Diamonds is a musical play with music by Noel Gay and book and lyrics by Clifford Grey and H.F. Maltby.
It opened at London's Gaiety Theatre on 25 February 1935.
[1] The New York Times reported that it opened to good notices and that its American star, Zelma O'Neal "scored a triumph".
One critic said of her pairing with co-star Reginald Purdell: "The spirit with which these two combine lends life and a touch of originality to the whole production".
