Her best-known recordings are the hits "Every Little Bit Hurts", "When I'm Gone", and "You've Made Me So Very Happy". The latter, which she co-wrote, was later widely popularized when it became a Top Ten hit for Blood, Sweat & Tears.

John William Weller is an English singer-songwriter and musician. Weller achieved fame in the late 1970s as the guitarist and principal singer and songwriter of the rock band the Jam, alongside Bruce Foxton and Rick Buckler. The band gained significant critical and commercial success in the United Kingdom, and were the most influential band of the mod revival of the late 1970s and early 1980s. Following the dissolution of the Jam at the end of 1982, Weller formed the Style Council with Mick Talbot, where he explored a wide variety of other musical styles, including pop, jazz, soul, hip hop, folk and classical. Although initially successful, the band's popularity declined in the late 1980s, leading them to break up in 1989. Weller began a solo career in the early 1990s, slowly re-establishing his commercial standing across his first four solo albums, Paul Weller (1992), Wild Wood (1993), Stanley Road (1995) and Heavy Soul (1997).
