That little mixer in the background had the first slider pots in that studio. Before that, everything was big rotary pots. As the junior copywriter, I got got to come along with the ad agency crew for a few jingle sessions in the afternoon (usually linked to a roast beef dinner at Ed's Warehouse) but the fun was late at night when I got to mess around with some musician friends. Doug Elphic who worked there as an assistant had some friends, Peter & Sunny and he would record them. My pet project was "Breakfast", Allan Fraser and Sue-Ellen Lothrop.
