The British pop group Edison Lighthouse was primarily the vehicle of session vocalist Tony Burrows; the group's lone top 40 hit "Love Grows (Where My Rosemary Goes)" from 1970, was one of four near contemporaneous U.K. Top Ten hit singles by Burrows under different names. The others were White Plains' "My Baby Loves Lovin'," the Pipkins' "Gimme Dat Ding," and the Brotherhood of Man's "United We Stand". In truth, Edison Lighthouse was merely the alias of songwriters and producers Tony Macaulay and Barry Mason, 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," Burrows left to pursue other projects, and Macaulay, who owned the rights to the Edison name, simply assembled another group to record under the alias. The second Edison Lighthouse barely cracked the U.K. Top 50 with the single "It's Up to You, Petula" before vanishing.
The group's name appears to be a weak pun on Eddystone Lighthouse although its etymology is uncertain.
