This week we hit the high note harmonies that crack glass and friendship as we uncover the very worst musical duos of all time. We're joined by one of the very best comedy musical duos - the charming, brilliant and award-winning political comics Jonny Donahue and Paddy Gervers aka Jonny and the Baptists. It's one hell of a journey as we discover sad tales of fraud, scatological Mexican metal bands and the imaginary bands that live in Paddy's head.
