Rhod Gilbert joins up with Soul II Soul legend Jazzie B in a ropey old tour bus for a road trip across southern England to discover the UK's best part-time band.

This is no ordinary talent show - the film follows Rhod and Jazzie as they drop in on bands playing in rehearsal spaces, bars, barns and front rooms. The tour takes them to Somerset where they meet a six-piece country and western outfit the Redhillbillies. Fronted by husband (hedge repairer Tom) and wife (district nurse Jo), the band have 42 children and grandchildren between them so have a ready-made audience at their weekly gigs.

Rhod faces an anxious trip to Bournemouth to hear Jazzie's favourite type of music, dub reggae. In a potentially awkward and intimate gig in the keyboard player Dave's front room, Dubheart aim to impress the Soul II Soul legend. Over in Stroud, the pair meet a guitar-based four-piece called Russian Flying Squirrel - formed of dads who met at their kids' school gates. They've yet to play a gig despite honing their musical skills for over three years.

At the end of the road trip, Jazzie selects five acts to play the biggest gig of their lives at the Scala in London, where they'll battle it out for a place in the grand final, and the coveted title of the UK's Best Part-time Band. Show less
