Yet another PBS Pledge Drive where-are-they-now music special, this one devoted to "'70s Pop". A good one-third of it was recycled from the previous Disco Specials (KC, Taste of Honey) but some new perfs from Orleans, John Ford Coley (without England Dan), Starland Vocal Band -- it was quite Gaz-tastic. Highlight: Andy Kim, in full '70s Neil Diamond-lookalike mode (he's clearly had work done and dyes his hair raven-black), doing "Rock Me Gently".
