According to Wikipedia, "In December 1987, (original lead vocalist John) Spence committed suicide several days before the band was to play a gig at The Roxy Theatre for record industry employees. No Doubt disbanded but decided to regroup after several weeks with Alan Meade taking over vocals. When Meade left the band, Gwen replaced him as lead singer, while No Doubt continued to develop a live following in California."
Was this the first gig post-John Spence?
