Lion Jamie Roberts joins Manic Street Preachers on stage 29 June 2013 Last updated at 09:15 Rugby international Jamie Roberts took time out from Lions duty in Australia to join Welsh rock stars the Manic Street Preachers on stage. The centre has yet to feature in the Lions test matches because of a hamstring injury. But he forgot his troubles and strummed guitar as the band played at Melbourne's Festival Hall. The Manics had lined up a series of concerts Down Under to coincide with the Lions 2013 tour. Roberts, 26, who qualified as a doctor after finishing his medical studies at Cardiff University earlier this summer, posted a picture of himself performing with the trio on his Twitter feed. He said it was "one of the best experiences I've ever had. Incredible. Many fans attending the gig shared their own photos of the rugby star's special guest appearance via Twitter. The Manics had previously admitted designing their Australian tour around the Lions matches. Nicky Wire told BBC Radio Wales the tour was "an amazing once in a lifetime opportunity." The Lions face the Wallabies in Melbourne in Saturday's Second test. Roberts, who is leaving Cardiff for Racing Metro, has been left out of the rugby test team with a hamstring strain.
