 The Remains were so popular in 1965 that the owner of the Rathskeller was forced to open up the basement for the first time to the overflow crowds that the Remains attracted.Sixties-style live music was phased out at some point, and the Rathskeller reverted to a simple restaurant until 1974.Upon reopening to music, the Rat promoted itself as the "Locus of Boston Rock and Roll,".
