Frank Sinatra, Dean Martin and Sammy Davis Junior. The names are synonymous with Fifties cool. Well into the Sixties, the stars of the original Ocean's Eleven and the greatest crooners of the 20th Century owned the world of showbiz.

The seductive trio, dubbed the rat pack, were inseparable friends and superb entertainers with voices to match. While their days were spent largely on film sets, by night they would play at the glamorous Sands Nightclub in Las Vegas, crooning and quipping their way through performances. Now a typical night at the legendary Sands is recreated for the stage.

"It was all about booze, broads and having a good time," says Henry Prego, the American actor who plays Frank Sinatra in this Olivier Awards-nominated production, straight from the West End.

"Tickets were like gold dust. They made the Sands Hotel the hottest joint in Vegas."

The show celebrates the Rat Pack's talent and friendship, their inimitable style and some of the finest music and songs ever recorded.

Some of the classic songs performed include I've Got You Under My Skin, My Way, Lady Is A Tramp, Fly Me To The Moon and Mack The Knife.

Henry has been called the "best Sinatra tribute artist in the business".

And his looks and mannerisms are spot on with a voice as smooth as old Blue Eyes himself. He grew up listening to The Beatles, Led Zeppelin and other rock stars of his generation but discovered swing in his early-30s.

He was instantly converted, chucked out the electric guitar and took up jazz. While waiting tables in California, he was called for an audition in Las Vegas where a similar show was playing.

He got the part as Frank Sinatra and stayed for three years. But ready for a change, he swapped Las Vegas for London and has been on the road in this production since January.

"It's a much better and bigger production," he says. "The lighting, the big band, the dancers - the whole show is spectacular. It's the closest you will get to experiencing the real thing."
