Ever heard of quadraphonic stereo? Of course you haven't... you're not dinosaurs! But when I saw the new Joan Baez song lesson I let out a little yelp. "Diamonds and Rust" was the first quad stereo album I ever bought. It was one of the last ones too as quad, AKA four-track stereo, didn't last too long.
I'm looking forward to the song lesson... just as soon as the lessons show up. That problem is back again.
