Quirky troubadour Jonathan Richman, the former Modern Lovers frontman who recently had a role in the film "There's Something About Mary," appeared on Saturday's (Sept. 26) season-premiere episode of "Saturday Night Live." Richman performed after a skit featuring the movie's star, Cameron Diaz. Musical guests the Smashing Pumpkins also made a non-musical cameo during one of the show's skits.
