The Bay City Rollers were a Scottish pop band of the 1970s. Their youthful, clean-cut image, distinct styling featuring tartan-trimmed outfits, and cheery, sing-along pop hits helped the group become among the most popular musical acts of their time. For a relatively brief but fervent period (nicknamed "Rollermania"), they were a worldwide sensation.

Bassist Alan Longmuir, his younger brother Derek Longmuir, a drummer, along with school mate, lead singer Gordon "Nobby" Clark founded the group in Edinburgh, Scotland in 1967, as The Saxons.
