Edison Lighthouse has been played on NTS in shows including Yesterday's News, featured first on 14 August 2019. Songs played include Love Grows (Where My Rosemary Goes).

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, with session vocalist Tony Burrows' vocals on the hit 'Love Grows', although members of the group Greenfield Hammer were eventually brought in to perpetuate the image of a real working band.

After the success of "Love Grows", Fradkin returned from New York City to join this newly formed British group as an original member of Edison Lighthouse. The recording of "Love Grows" proved to be a worldwide success reaching number five in the USA on the Billboard singles hot 100 chart in February 1970 and became a number-one hit the world over, selling a total of eight million copies. In fact, for the whole of 1970 it was the number-two selling pop record in the U.K.
