Abbeyshrule Air Shows in the mid '70s had something very similar. Except the rubbing the wing tips of the ground bit ! Even used the Piper Cub. Racking my brain to remember who flew the stunt, possibly one of the van Lonkhuyzen brothers.
A few hours sitting in The Rustic Inn might help me remember ! Suspect Ted McGoey, Dave Bruton or Brian Dillon have the answer.
