Leslie Richard McKeown was a Scottish singer, best known as the lead vocalist of the pop rock band Bay City Rollers during their most successful period in the 1970s. The band's original lead singer, Gordon "Nobby" Clark, decided to leave the band in 1972 after fulfilling his touring obligations and McKeown joined the band as their lead vocalist by 1973 and began to re-record his vocals on tracks including "Remember" and "Saturday Night", which then became a US number 1 hit. The band released their debut album, Rollin once McKeown had become their established lead singer, and the album reached number one in the United Kingdom where it finished the year as the 16th best selling album and subsequently was certified Platinum. The band charted with the singles "Shang-a-Lang" and "Summerlove Sensation". Their second album, Once Upon a Star, was supported by the release of the single "Bye, Bye, Baby" in February 1975. The single became the best-selling single of the year in the United Kingdom. In 1975, the band secured their North American breakthrough with the release of "Saturday Night" after receiving backing from music executive Clive Davis.
