Negativeland (Mark Hosler, Chris Grigg, Don Joyce, David Wills and Richard Lyons) was a band, but they also produced a live radio show "Over The Edge".
One of these shows, broadcast on march 31, 1995, was a Zappa special, entitled "They S(h)aved Zappa's Moustache".
The show was made available on cassette, and a condensed version circulates on CDR.
