For many of us dedicated pervs, the artist known as Melanie’s quaintly risqué 1971 single “Brand New Key” will forever be wedded to Heather Graham’s skate-equipped nude scene in Boogie Nights. (Remember in A Clockwork Orange when Alex got horrible thoughts in his head whenever he heard Beethoven? This would be the opposite.) But her post-Woodstock anthem “Lay Down (Candles in the Rain)” and “Look What They Done to My Song, Ma” also remain emblems of turn-of-the-Seventies grooviness, or at least a brief intersection of folk-rock and Tin Pan Alley bounce. She lives in Nashville now, and she’s headlining this benefit for local space-music artist Tony Gerber and his family, who lost their home and belongings in the Nashville Flood — only to be told by their insurance company that their coverage had an exclusion clause for water damage. Gerber has also enjoyed a lucrative virtual side career for years as Cypress Rosewood on Second Life: you can contribute there by checking www.cypressrosewood.com.
