An event sponsered by WFIL AM radio in Philadelphia, in the early 70's. I was the lucky caller who won tickets. I must have been in 7th or 8th grade. I remember Jim Croce, Jose Feliciano, the O'Jays, and I think, the Raspberries, playing there. The most memorable things that I took away from that concert were the image of Jim Croce so joyously playing, not long before his untimely death, and the crowd snaking around the floor of the Civic Center in a massive "Love Train" as the O'Jays sang that hit. Philly was about to become a fantastic place to hear live music in the 70's, during the heyday of the Electric Factory music promotion group. I went to many concerts, mostly at the concrete echo chamber known as the Spectrum. J. Geils, Steely Dan, Loggins and Messina, Zeppelin, Foghat, Roy Buchannon, among so many others. Ruined my hearing, but what fun it was.
