Desperate for a way to communicate after losing his hearing, young Patrick Costello set his heart on becoming a musician. Ignoring the odds, empowered by his family and a karate grandmaster, Patrick won a banjo in a bet, salvaged a guitar from the trash and wandered into the city of brotherly love looking for a teacher. What happened next is an unbelievable true story of chasing improbable dreams, kind-hearted strangers, the IRA, Taoism, the Philadelphia Mummers, and unconditional love. Just This Banjo will make you laugh, cry and maybe inspire you to pick up an instrument yourself.
