John Cale Has A Secret

During a discussion with Professor Katkin about the 2008 WFMU setlist and the two Velvet Underground tracks included in the set, I mentioned I've been on a big Velvet Underground kick lately.  In response to this, Ken sent over this little gem of John Cale on the September 16, 1963 episode of I've Got a Secret.  His secret centered around his participation in an 18 hour 40 minute piano performance, the first full length presentation of Erik Satie's "Vexations".  As the YouTube poster who uploaded the video mentions, the other pianists who participated in the performance were John Cage, David Tudor, Christian Wolff, Philip Corner, Viola Farber, Robert Wood, MacRae Cook, John Cale, David Del Tredici, James Tenney, Howard Klein (the New York Times reviewer), Joshua Rifkin, and two reserves.  The group played the piece, which is only three lines long, the required 840 times on September 9, 1963, from 6 p.m. to 12:40 p.m. the following day.  Seated also on the I've Got a Secret stage was Off Broadway actor, Karl Schenzer, who's secret was that he was the only person to stay for the entire piano concert.
