The Rat Pack is Back in Las Vegas, this time Frank Sinatra, Dean Martin, Sammy Davis, Jr., Joey Bishop, Peter Lawford are at the Crown Theater at the Rio Hotel and Casino. This is one for the ages, its what Vegas was built on. There was a time when Frank would perform then have someone's legs broken later than night, or so the rumors go. This is nostalgic Las Vegas at its core and at a really good price. Take in the free Show in the sky at the Rio and the Rat Pack and call it a night.
