After joining the Bay City Rollers in November 1973, the band, with Les McKeown on lead vocals, shot to superstardom. "Remember", the Bay City Rollers' first single with Les McKeown's vocals, shot up the UK charts to No. 6 and was quickly followed by "Shang-A-Lang", "Summerlove Sensation" and "All Of Me Loves All Of You" all hitting the Top Five. "Bye Bye Baby" was their first UK Number One in May 1975 followed by "Give A Little Love" in July. Their first US single, "Saturday Night", went straight to the top number 1 spot of the Billboard charts, and their first British album, "Rollin'" was the first debut album to top the number 1 position in the charts.
The Bay City Rollers released many more Top 10 songs over the next two years including "I Only Wanna Be With You", and "You Made Me Believe In Magic". Between 1975 - 1978, they toured all over the world and played to sold out crowds in the USA, Japan, Great Britain, Europe, New Zealand and Australia.
