Which 1970 song made Edison Lighthouse a UK one-hit wonder?

“Love Grows (Where My Rosemary Goes)” made Edison Lighthouse a UK one-hit wonder by reaching number one in 1970.

The song was written by Tony Macaulay and Barry Mason, professional songwriters associated with the British pop scene. Its lyric praises a woman whose appeal comes from warmth and personality rather than conventional glamour. The bright arrangement and instantly repeated chorus gave it the polished, accessible sound of early-1970s British pop.

Edison Lighthouse was originally assembled as a studio project, with vocalist Tony Burrows providing the lead vocal on the hit recording. Burrows also sang on several other recordings credited to different groups, which has contributed to confusion about the identity of the performers.

The title’s reference to “Rosemary” is part of the lyric’s fictional romantic portrait; it does not identify a famous historical person. The recording remains especially associated with the UK chart, where it spent five weeks at number one, while the group did not establish a comparable continuing career.
