The auction house Gotta Have Rock and Roll is auctioning several objects MJ, clothing, books, etc ... Predictably most of them come from your the Cascio family.
The most interesting could this DAT, one of the mixes of the unreleased song "Revenge" dated February 27, 1995.
There is also a CD with the unreleased title (and so far, unknown) of "If I Were To Wish". It is dated December 5, 2002 and on the cover can be read Frank, Angel and Buxer names (logically would be Frank and Eddie Cascio and Brad Buxer).
Outside the music business, there is a private tape of Liz Taylor, Larry Fortensky and MJ appear in Singapore. There are images of three in the hotel, private jet, visiting a zoo, etc ... Some 50 minutes. Sold by Frank Cascio.
