Alan Longmuir, one of the founding members of the Bay City Rollers, has passed away at the age of 70.
The Edinburgh-born musician was surrounded by family and friends when he died of a 'short illness', the BBC reports.
Longmuir formed the Bay City Rollers with his brother Derek, and they went on to find huge success in the 1970s.
Many have taken to Twitter to mourn the loss of the music great.
The Bay City Rollers became teen sensations in the UK and the US with hits like Bye Bye Baby and Shang-a-Lang.
Our thoughts are with Alan's family and friends.
