Anderson was asked to perform at the PG School of Rock Music and agreed. Now he's backed out of the gig due to "health reasons." TMZ heard that the reason was that Jon's spiritual advisor told him not to perform until 2008, allegedly causing him to pull out of the Yes Reunion Tour as well. His advisor needs to tell Jon that no one cares!
We checked with Anderson's rep, who tells us that Jon pulled out due to health reasons, citing a flu, and denied any of the "spiritual advisor" stuff, saying that the tour is still "in the works."
