Hi, ahwile back I acquired 2 quad 45s on CBS label affiliates. One was Art Garfunkle's "All I Know/I Shall Sing" and the other "Frankenstein/Free Ride" by Edgar Winter. I had never seen any quad 45s before! Are there more? I know these were both sent to a radio station, but the labels were store color style. I assume the Garfunkle tracks are the same as on my quad Lp. I wonder if the Winter ones are? "Frankenstein" has a horrible edit into the middle sound effects. POORLY mixed would be an understatement. I assume it's that way on the Lp too. This is my first post. Thanks, Clark
