I know of at least two planned comedy fundraising shows this weekend for the family of the late comedian Cain Lopez, who died last week from cancer at the age of 30. Funeral arrangements for Lopez will be next Monday-Tuesday in Vacaville, Calif. Richard Villa will host a tribute show late Friday, July 17, at the Hollywood Improv on Melrose, with a scheduled lineup that's set to include Joey Medina, Joey Diaz, Jeff Garcia and Willie Barcena. Pepper Belly's in Fairfield, Calif., will go ahead with its already-planned fundraiser as a tribute show on Sunday, July 19.
