Must Read: Comedian Joey Bishop, last of Frank Sinatra's Rat Pack, dead at 89

LOS ANGELES - Joey Bishop, the stone-faced comedian who found success in nightclubs, television and movies but became most famous as a member of Frank Sinatra's Rat Pack, has died at 89.

He was the group's last surviving member. Peter Lawford died in 1984, Sammy Davis Jr. in 1990, Dean Martin in 1995 and Sinatra in 1998.

Bishop died Wednesday night of multiple causes at his home in Newport Beach, publicist and longtime friend Warren Cowan said Thursday.

The Rat Pack became a show business sensation in the early 1960s, appearing at the Sands Hotel in Las Vegas in shows that combined music and comedy in a seemingly chaotic manner.

Reviewers often claimed Bishop played a minor role, but Sinatra knew otherwise. He termed the comedian 'the Hub of the Big Wheel,' with Bishop coming up with some of the best one-liners and beginning many jokes with his favorite phrase, 'Son of a gun!'

'He was the perfect match for the Rat Pack. He fit right in like an old shoe,' Hollywood's honorary mayor, Johnny Grant, said Thursday.

The quintet lived it up whenever members were free from their own commitments. They appeared together in such films as 'Ocean's Eleven' and 'Sergeants 3' and proudly gave honorary membership to a certain fun-loving politician from Massachusetts, John F. Kennedy, at whose inauguration gala Bishop served as master of ceremonies.

The Rat Pack faded after Kennedy's assassination, but the late 1990s brought a renaissance, with the group depicted in an HBO movie and portrayed by imitators in Las Vegas and elsewhere. The movie 'Ocean's Eleven' was remade in 2003 with George Clooney and Brad Pitt in the lead roles.

Bishop defended his fellow performers' rowdy reputations in a 1998 interview.
