Chan was attending a performance by Taiwanese singer/songwriter Jonathan Lee when he unexpectedly took to the stage, starting swearing and hassling the band and Lee.
Chan's pop star son Jaycee Chan, who counts Lee as musical inspiration, has also repeatedly apologized for his father's bizarre behavior.
The rather embarrassed Rush Hour star later admitted to leading Hong Kong radio show host Candy Chea that he was drunk when he jumped onstage, explaining that he "forgot there were so many people watching."
Chea revealed their conservation on her show earlier today, saying, "But Chan also said this was his first time, and it had never happened before."
