The idea, says former Creedence Clearwater Revival bassist Stu Cook, began simply enough.

"Back in the mid-'90s, I relocated from southern California up to Lake Tahoe in northern Nevada, and Doug [Clifford, Creedence's former percussionist] had been living there with his family for 15, 20 years. We hadn't lived in the same area for decades, and we started hanging out every day, and playing music, and just talking about how much fun it was, and how it felt to play together again.

"So we were bound to get into trouble," says Cook with a laugh. "And goodness, look what happened."
