Edison Lighthouse was a UK pop group, initially a studio-only assemblage that included Tony Burrows and songwriter/record producers Tony Macaulay and Barry Mason. The band are best known for their 1970 UK chart-topper and million-selling record, "Love Grows (Where My Rosemary Goes)". They are widely regarded as a one-hit wonder, with only two songs entering any chart worldwide: "Love Grows (Where My Rosemary Goes)" and "It's Up to You, Petula".
