Karl Koch 	Though it is certainly inappropriate to classify Koch's work with Weezer as "sitting in," as he has contributed in fundamental ways to the group's aesthetic and development over their entire career, Koch has had several more concrete contributions to Weezer's output that warrant inclusion in this list. He has photographed countless Weezer performances, performed live with the band (most notably during the Memories Tour), directed six of the band's videos, three of Cuomo's solo videos, and one Special Goodness video, and produced, directed, and edited the band's only proper DVD release. He is the band's chief historian and documentarian. He appears on several Weezer recordings, most notably performing the percussion on "Butterfly," but also: "Undone - The Sweater Song" (spoken word intro and post-chorus, "piano madness" in outro), "Buddy Holly" (handclaps), "Across the Sea" (incidental noises), "The Good Life" (cymbal roll), "Don't Let Go" (backing vocals), "Last Chance" (unreleased; backing vocals), and the Karlophone remix of "The Prettiest Girl in the Whole Wide World" (engineer).	1992 - present 	YouTube link to "Say It Ain't So" music video, which features a cameo from Koch.
