Edison Lighthouse originated in England as an outgrowth of the successful U.K. group, The Flying Machine which had a U.S. top-five hit in November 1969 with "Smile a Little Smile for Me" featuring Les Fradkin on vocals, mellotron, organ, and guitar. The producer of that release assembled a new group for a new song called "Love Grows (Where My Rosemary Goes)". Edison Lighthouse was the alias of songwriters and producers Tony McCaulay and Barry Mason
