LISBON Lion Bertie Auld delighted an audience watching Celtic The Musical - by jumping on stage and having a boogie.

The fan favourite joined the cast of the hit show at the Pavilion on Friday night and the moment was shared in Celtic fan groups on social media.

Bertie can be seen joining in on a sing song of The Fields of Athenry and Depeche Mode's hit Just Can't Get Enough.

Bertie, 80, was a member of Celtic's famous Lisbon Lions who won the European Cup Final in 1967. Last year, the club celebrated the achievement of the 50th anniversary of the win.

The Maryhill-born midfielder was inducted into the Scottish Football Hall of Fame in 2009.

Celtic The Musical continues its run at the Pavilion until Saturday.
