Eric Bloom and Ian Hunter have shared several songwriting sessions, which yielded Spectres' "Goin' Through the Motions" and Revölution by Night's "Let Go." Eric returned in kind, and contributed backup vocals on Ian Hunter’s 1979 LP "You’re Never Alone with a Schizophrenic." Eric also sings a line on the 1986 "Stars" single, for the hunger relief "Hear 'n Aid" project, organized by Ronnie James Dio. "Stars" and its accompanying video featured a wide range of metal stars, including Spinal Tap, Yngwie Malmsteen and Ted Nugent. Most recently Eric sings on a Metallica tribute album, "Metallic Assault," doing "For Whom the Bell Tolls" with Al Pitrelli, Ansley Dunbar and Tony Franklin. Other Eric projects: Spoken introduction on "Don't Fear the Remake" by Too Hip for the Room.

Buck Dharma plays guitar on three songs on Kasim Sulton's (Utopia) first solo outing, "Kasim" (EMI-America ST-17063). Buck also recorded a song (and video) with the upstate New York band Blotto, which appears on their "Combo Akimbo" album. "Metal Head" is a hilarious take-off on the hard core Heavy Metal fan, and although the album cut is great, the video takes it to new heights and is the best way to enjoy the song. Buck contributes the guitar solo in the song, and cameos in the video as a frustrated wannabe guitarist. He also made a guest appearance with Blotto onstage for "Metalhead" in 1983. Another Dharma appearance can be found on a syndicated live radio show, The Source, making a guest appearance with Pat Travers on the encore, a version of Cream’s "Sunshine of your Love." Buck appears on Les Vegas' (Les Braunstein, original Soft White Underbelly vocalist) 7" single, "Dark Angel" and his recently released CD, "Fools Gold." Other Dharma appearances: "Stars", Hear 'n Aid single "Thumb" from album by Christy Jefferson "ZKG" by Tommy Zvoncheck "El Sol" from To Helen With Love CD "All Time Greatest Hips" & "Don't Fear the Remake" by Too Hip for the Room

Allen’s contributions can also be found on many of Patti Smith’s albums, and on John Cale’s 1979 LP "Music For A New Society." Sandy Pearlman often used Allen as a studio musician for his many production projects in the seventies.
