The series showcased new musical artists to whom other comedy-variety shows rarely gave airtime, due to the nature of their music or their political affiliations. George Harrison, Ringo Starr, Joan Baez, Buffalo Springfield, Cass Elliot, Harry Belafonte, Cream, Donovan, The Doors, Glen Campbell, Janis Ian, Jefferson Airplane, The Happenings, Peter, Paul and Mary, Spanky and Our Gang, Steppenwolf, Simon and Garfunkel, The Hollies, The Who and even Pete Seeger were showcased on the show, despite the advertiser-sensitive nature of their music.
