Peter and Roughie are joined by Tam Cowan and special guest Gary Harkins as the Partick Thistle midfielder lets slip about an elaborate prank involving a dodgy licence plate, fake police reports and a Jags hero doubling up as a lawyer.   He also reveals his pride in getting the better of Celtic skipper Scott Brown, which big screen star he called a teammate at school, his THIRTEEN club career and the superpower he would choose given the chance.   Roughie also divulges all about a night out with music legend Rod Stewart and Tam Cowan recalls an impromptu meeting with movie icon Al Pacino in Las Vegas.
