This UK conglomeration was essentially a vehicle for session singer Tony Burrows, who also sang with White Plains, the Brotherhood Of Man and the Pipkins. The backing musicians were originally part of a band called Greenfield Hammer before they became a studio re-creation and hit group. The Tony Macaulay /Barry Mason composition Love Grows (Where My Rosemary Goes) provided the breakthrough in 1970 and zoomed to number 1 in the UK and also hit the US Top 5. While this was occurring, Burrows had already moved on to other projects, leaving his backing musicians to continue under the name Edison. Macaulay, meanwhile, still owned the name Edison Lighthouse and conjured up another line-up with that title for recording and touring purposes. The manufactured spin-off group failed to exploit their chart-topping name, although they did manage to scrape into the lower rungs of the UK Top 50 with a weak follow-up, Its Up To You Petula.
