The Bay City Rollers were a popular Scottish pop band of the 1970s.

The group had five members:

• Eric Faulkner (guitar)
• Alan Longmuir (bass)
• Derek Longmuir (drums)
• Les McKeown (vocals)
• Stuart Wood (guitar)

Most of the band members came from Prestonpans , East Lothian. It was here that they were discovered by potato merchant Tam Paton, who became their manager. In later years, Paton was convicted of paedophile offences.

Their Scottish identity was a major factor in their marketing, and they were one of few groups whose fans had a completely distinctive style of dress, the main elements of which were mid-calf-length tartan trousers and tartan scarves.

They had several hits that made to the Top 3 of the British charts, and for a period had their own television series, entitled Shang a Lang (the title of one of their hits). By Spring of 1975, the Rollers were one of the highest selling acts in Britain, and announced their next single, a cover of the Four Seasons' "Bye Bye Baby". The single went to number 1 in March '75 and sold a million copies.

They had a dedicated following of teenage girls that was so intense, that the media called it "Rollermania". However, they were never popular with music critics nor the male audience and their popularity quickly waned.

The band members have said they chose their band's name by throwing a dart at a map of the United States. The dart landed on the map near the community of Bay City, Michigan.

A popular playground chant of the time went (to the tune of This Old Man):

B-A-Y, B-A-Y,

B-A-Y, C-I-T-Y,

With an R-O-double-L, E-R-S,

Bay City Rollers are the best!

Other hits include:

• Bye, Bye Baby
• Saturday Night
