Joe Elvin (born Joseph Peter Keegan; 29 November 1862 – 3 March 1935) was an English comedian and music hall entertainer and a Founder of the Grand Order of Water Rats, a show business charity.
He made his début in pantomime at Brighton's Theatre Royal in 1871 and began his music-hall career the following year as a juvenile comic and clog dancer at Crowder's in Greenwich.
[4] The two frequently appeared together as 'Keegan and Elvin', including at the 1887 variety performance benefit for Charles Ash at the Royal Victoria Hall in Lambeth.
In 1889 Elvin was a founder with Jack Lotto of the Grand Order of Water Rats, a show business charity which began life when a betting syndicate that had grown up around a trotting pony owned by Elvin agreed to donate any winnings to charity, gaining its name when someone referred to the pony during a rainy trip to the Derby as looking more like a water rat.
Elvin is buried in Bandon Hill Cemetery in Wallington in Surrey beside his friends and fellow music hall artistes Eugene Stratton and Jack Lotto.
