The Bay City Rollers are a Scottish pop rock band known for their worldwide teen idol popularity in the 1970s. They have been called the "tartan teen sensations from Edinburgh", and "the first of many acts heralded as the 'biggest group since the Beatles'". The group's line-up had many changes over the years, but the classic line-up during its heyday included guitarists Eric Faulkner and Stuart John Wood, singer Les McKeown, bassist Alan Longmuir, and drummer Derek Longmuir. The line-up in 2018 includes guitarist Stuart John Wood (Woody), singer Ian Thomson, bassist Marcus Cordock and drummer Jamie McGrory.
