Rodney Slater, who was the alto saxophone player in band, owned two parrots who they all enjoyed teaching to swear. The Parrots were named Pearl and Freddy after the entertainers Pearl Carr and Teddy Johnson.
This song was later used on a Cadbury's chocolate advert still sung by Vivian Stanshall but changed to "My Cadbury's Parrot."
