Actor and former Saturday Night Live star Will Forte sat in with Guster this past Tuesday in Hyannis, MA. Forte emerged during the group’s show at the Cape Cod Melody Tent to sing on a cover of Air Supply’s “All Out of Love.” The actor/comedian apparently met Guster frontman Ryan Miller at a Bob Dylan tribute earlier this year. After hearing that Forte was in the Cape Cod area shooting a movie, the band invited him to sit in on the comedic cover. Guster will perform at New York’s Central Park SummerStage tonight.
