"What people don't realise is that Sirius Black is a false name. The man people believe to be Sirius Black is actually Stubby Boardman, lead singer of popular singing group The Hobgoblins, who retired from public life after being struck on the ear by a turnip at a concert in Little Norton Church Hall nearly fifteen years ago."
-- Doris Purkiss in The Quibbler (OP10)
The Hobgoblins was a wizarding musical group whose lead singer, Stubby Boardman, retired in 1980 after an incident involving a turnip (OP10).
The band was mentioned in a Quibbler article in the summer of 1995 when a Doris Purkiss of Little Norton insisted that accused killer Sirius Black was actually Stubby Boardman, who was having a romantic dinner with her when the murders supposedly occurred (OP10).
