Here in Glendale there is a really nice Italian restaurant, Fratelli's, which subscribes to a music channel that features Frank Sinatra, Dean Martin, Tony Bennett, Vic Damone, Bobby Darin, Al Martino, Eydie Gormé, Perry Como and other Italian-American singers. Those songs do create a mood.
Exactly. In a packed restaurant on a weekend night, playing the tunes from the 40's and 50's (based on the artists you mentioned) in 2013, would scour the place out.....not a chance! Good for Fratelli's. Same should apply to radio with the classics.
