The Irwin Steinberg Aggregation

Vocal ensemble lead by the Phonogram/Mercury's president Irwin Steinberg, credited only on 2 songs of Tom T. Hall: "That Song Is Driving Me Crazy" and "I like Beer". Steinberg flew from Chicago to attend Hall's recording session in Nashville and recruited some member of the Nashville's office staff (plus some casual people), to record the backing vocals of the songs cited.
