Tuli Kupferberg, one of the founding members of The Fugs, is dead at age 86.
I haven't heard the band's music, but I've been curious about The Fugs for years because the band is mentioned in ILLUMINATUS! (e.g. in this passage "Simon [Moon] began humming as he drove; Joe [Malik] recognized the tune as 'Ramses II Is Dead, My Love'." Page 124). The same song also is mentioned in the THE HOMING PIGEONS.
Here is the Wikipedia and Kupferberg, and here is Wikipedia on The Fugs. Robert Christgau's "Consumer Guide" reviews are here.
