Hot Legs: Celtic’s win over Barcelona makes grown rock star cry (video)

Those unfamiliar with the 1970s might not know that Rod Stewart fans once roamed the Earth in great herds, and he’s even somewhat popular today — he’s sold more than 265 million records worldwide. You may not have known that his father was born in Scotland, and Stewart is a huge Celtic fan — which makes that team’s 2-1 upset Champions League victory over Barcelona (snapping Barcelona’s 12-match winning streak) a near religious experience for him.

So much so that Stewart, in the stands at Celtic Park on Wednesday, was seen on Sky Sports bursting into tears.

There had been a late scare when Barca star Lionel Messi scored in the 90th minute, but Celtic held on to mark its 125th anniversary with a memorable 2-1 win.

The victory puts Celtic on course to advance from the group stage to the knockout phase. Neil Lennon’s side is two points behind Group G leader Barca.

Stewart is one Celtic’s most devoted, and famous, supporters and makes mention of his love for the club in his hit song “You’re in My Heart.”
