EdSails... Not at Griffith Park but the Renaissance Festival or CSUN which was SFVSC when I began.
Yes, I remember it well. I first saw Steppenwolf at Devonshire Downs, as well as performing at the Matador games with the CSUN Field Band. If you ever listened to KCSN, I was on there from 1971 until 1975, first as a music programmer for the '3 to 5' Rock Show, then on air and finally as producer of my own jazz show.
