Swinging music of the era is also considered lounge and consisted of a schmaltzy continuation of the swing jazz era of the 1930s and 1940s, but with more of an emphasis on the vocalist. The legendary Rat Pack of Frank Sinatra, Dean Martin, and Sammy Davis Jr., along with similar artists such as Bobby Darin, Jackie Gleason, Wayne Newton, Louis Prima, Sonny King, and Sam Butera are notable examples. The music of Burt Bacharach was soon featured as part of many lounge singers’ repertoires. Such artists performed mainly at featured lounges in Las Vegas casinos.

Lounge singers have a lengthy history stretching back to the decades of the early twentieth century. The somewhat derisive term lounge lizard was coined then, and less well known lounge singers have often been ridiculed as dinosaurs of past eras[3] and parodied for their smarmy delivery of standards.[4] In any event, these lounge singers, perhaps performing in a hotel or cocktail bar, are usually accompanied by one or two other musicians, and they favor cover songs composed by others, especially pop standards, many deriving from the days of Tin Pan Alley.
