An interesting article about the famous escape from Alcatraz in 1962. Frank Morris would play an accordion to mask the noise as John and Clarence Anglin worked at digging out a ventilation duct. Morris apparently had a concertina as well:
"On the night of June 11, 1962, they crawled through the hole in their cell wall and then up a network of piles to the prison roof. They then slide down a smokestack and left the island on a raft made of more than 50 raincoats and inflated with a small concertina, which was used as an improvised bellows."
