Werewolves of London Werewolves of London "Werewolves of London" is a rock song performed by American singer-songwriter Warren Zevon. It was composed by Zevon, LeRoy Marinell and Waddy Wachtel and was included on "Excitable Boy" (1978), Zevon's third solo album. The track featured Fleetwood Mac's Mick Fleetwood and John McVie on drums and bass respectively. The single was released by Asylum Records and was a top 40 US hit, reaching No. 21 on the Billboard Hot 100 that May. The song began as a joke by Phil Everly (of The Everly Brothers) to Zevon in 1975, three years before the recording sessions for
Warren Zevon the only guest for the entire hour. The band played "I'll Sleep When I'm Dead" as his introduction. Zevon performed several songs and spoke at length about his illness. Zevon had been a frequent guest and occasional substitute bandleader on Letterman's television shows since "Late Night" was first broadcast in 1982. He noted, "I might have made a tactical error in not going to a physician for 20 years." It was during this broadcast that, when asked by Letterman if he knew something more about life and death now, he first offered his oft-quoted insight on dying: "Enjoy every sandwich."
