Short answers, pulled from the story.
Ringo Starr's real name is Richard Starkey. He was born on the 7th of July 1940 at 9 Madryn Street in Dingle, Liverpool. He adopted the stage name Ringo Starr when he joined Rory Storm and the Hurricanes, deriving it from the rings he wore and a nod to country and western music.
Ringo Starr replaced Pete Best in August 1962 because the other Beatles felt Best did not fit in with the group, and producer George Martin was dissatisfied with Best's playing. Beatles manager Brian Epstein delivered the news to Best on the 16th of August 1962. Starr first performed with the Beatles two days later, on the 18th of August, at a horticultural society dance at Port Sunlight.
Ringo Starr sang lead vocals on "Yellow Submarine", which was the Beatles' only British number-one single with him as lead singer, and on "With a Little Help from My Friends" from Sgt. Pepper's Lonely Hearts Club Band. He also sang lead on "Boys", "Act Naturally", "Honey Don't", "Matchbox", "I Wanna Be Your Man", "Good Night" and "What Goes On", as well as his own compositions "Don't Pass Me By" and "Octopus's Garden".
Ringo Starr wrote "Octopus's Garden" while on holiday in Sardinia, staying on a boat loaned by actor Peter Sellers after briefly quitting the Beatles during a difficult recording period. A chef served octopus at lunch, which Starr refused to eat; a subsequent conversation with the ship's captain about the animal inspired the song. He wrote it on a guitar during the trip, and it appeared on the Beatles' Abbey Road album.
Ringo Starr's most successful solo album is Ringo, released in 1973 and produced by Richard Perry. It reached number two in the US and number seven in the UK.
