Having jammed as a trio in 1992, Hagar, drummer David Lauser, and Van Halen bassist Michael Anthony formed the harmony-singing rock band Los Tres Gusanos (in English, The Three Worms) in 1993. Playing a mixture of Hagar, Van Halen, and cover songs at Cabo Wabo and in San Francisco the band got together a few times a year. Initially active until 1996, Los Tres Gusanos regrouped in 2002, then again in 2005, and has performed together many times since. Lauser has gone on record to say, "Los Tres Gusanos will never die and rumors abound that they may resurface in Cabo soon."
