I've heard of the Rat Pack, from the 1950s. Were there arguments or fights in the group? Sinatra et al.

The Rat Pack, led by Frank Sinatra, was a group of celebrity friends and colleagues who performed together in clubs and at private events in the 1950s and 1960s. There were rumored to have been occasional arguments and fights in the group, especially between Sinatra and Peter Lawford, which likely stemmed from the well-documented feud between Sinatra and Lawford's wife, actress Janet Leigh.
