Rave Un2 The Joy Fantastic, 1999
In 1999, No Doubt reached out to Prince, asking him to contribute vocals to their song "Waiting Room." He did much, much more than that, revising the entire track, adding keyboards and backing vocals and earning a co-writing credit in the process. In exchange, Gwen Stefani lent her vocals to "So Far, So Pleased," a pop-rock single as bright, crunchy and candied as a bowl of Apple Jacks. The song was a clear highlight of the Rave Un2 the Joy Fantastic album, which also featured cameos from a motley crew of musicians ranging from Chuck D to Sheryl Crow to Maceo Parker.
