Keep Your Seats, Please

Despite being on his uppers, George is still prepared to pawn his beloved banjo in order to help his girlfriend save her niece from the orphanage. Help seems to be at hand when George is left a fortune by his old auntie, but unfortunately his inheritance is hidden inside a chair which has already been auctioned off! Can George and his chums track down his rightful due before his grasping solicitor (Alastair Sim, in an early film appearance) snatches the lot?
