Coco Montoya

For the music career of singer/guitarist Coco Montoya, thank the persistence of John Mayall.

It's not merely that Mayall called Montoya to ask him to join the legendary Bluesbreakers band in the early 1980s. It's that he called back when Montoya - who had quit music as a profession after a stint drumming for Albert Collins in the 1970s - hung up on him.

"I didn't think it was him," Montoya said in a recent phone interview, promoting his Saturday bandshell performance at the Mississippi Valley Blues Festival. "I was bartending at a British pub. ... So I thought it was some of the English cats in there teasing me. ... He called back. 'No, this really is John Mayall. ... Do I have to come down there ... ?'"
