If the phrase "the show must go on" has ever applied, it applies to the San Francisco Mime Troupe's Oil and Water. After five decades of creating theater that lampoons the powerful, the Tony award-winning group almost had to cancel its summer season. A decline in grant funding and an increase in park fees left the outfit $40,000 short of the funds needed for its annual run in Bay Area parks. Unwilling to hang up their costumes, the members of the Mime Troupe slashed costs for a slightly leaner season and waged a grassroots fundraising campaign that saved the show. Lost in the hubbub has been the fact that the Mime Troupe is doing something new and exciting this year: Oil and Water is actually two shows. Both are presented as one-act plays and deal with climate change. "Crude Intentions" follows a pair of jaded San Francisco restaurateurs forced to confront a certain Bay Area oil company known for its less-than-wholesome dealings in Ecuador. "Deal With the Devil" is a comic take on a future America that can't wean itself off of fossil fuels, even when facing environmental devastation. The show goes on indeed, as political and relevant as ever.
