In February 1998, Robert again collaborated with Reeves Gabrels in the studio, co-writing, singing and playing on the song "Yesterday's Gone" (eventually finding its way to CD release in 2000). The following month, Smith was again recording solo between RAK and Outside studios, assisted this time by co-producer Paul Corkett, whose production credits included Nick Cave, Björk, Placebo, Tori Amos and Suede. These sessions produced "More Than This" (not to be confused with the Roxy Music song) for ', and a cover of Depeche Mode's "World in My Eyes" for the tribute album "For the Masses". Again, both were released under the name of the Cure, but were essentially Robert Smith solo recordings. Smith said: Having made a guest appearance on an episode of "South Park" earlier in the year (see → '), Smith again collaborated with Trey Parker under the name COGASM, featuring Reeves Gabrels and Jason Cooper, releasing the track "A Sign from God" for the film "Orgazmo". Smith's contribution to "Yesterday's Gone" appeared on Gabrels' solo album "Ulysses (Della Notte)" released in 1999 via Internet and in 2000 on CD by E-magine Music.
