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 that 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 of 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.

“Are we remembered as being drunk and chasing broads?” he asked. “I never saw Frank, Dean, Sammy or Peter drunk during performances. That was only a gag. And do you believe these guys had to chase broads? They had to chase ‘em away.”

Away from the Rat Pack, Bishop starred in two TV series, both called “The Joey Bishop Show.”

The first, an NBC sitcom, got off to a rocky start in 1961. Critical and audience response was generally negative, and the second season brought a change in format. The third season brought a change in network, with the show moving to ABC, but nothing seemed to help and it was canceled in 1965.

In the first series, Bishop played a TV talk show host.

Then, he really became a TV talk show host. His program was started by ABC in 1967 as a challenge to Johnny Carson’s immensely popular “The Tonight Show.”

Like Carson, Bishop sat behind a desk and bantered with a sidekick, TV newcomer Regis Philbin. But despite an impressive guest list and outrageous stunts, Bishop couldn’t dent Carson’s ratings, and “The Joey Bishop Show” was canceled after two seasons.

Bishop then became a familiar guest figure in TV variety shows and as a sub for vacationing talk show hosts, filling in for Carson 205 times.

He also played character roles in such movies as “The Naked and the Dead” (“I played both roles”), “Onion-head,” “Johnny Cool,” “Texas Across the River,” “Who’s Minding the Mint?” “Valley of the Dolls” and “The Delta Force.”

While most members of the Sinatra entourage treated the great man gingerly, Bishop had no inhibitions. He would tell audiences that the group’s leader hadn’t ignored him: “He spoke to me backstage; he told me ‘Get out of the way.’ “

When Sinatra almost drowned filming a movie scene in Hawaii, Bishop wired him: “I thought you could walk on water.”
