Seventy-year-old Groucho Marx showed his youth as he did the frug with Diana Ross, 22-year-old lead singer of the supremes, a female rock n roll group, at an outdoor barbecue party. The party was given by actor-singer Bobby Darin at his Bel-Air home in Los Angeles on August 19, 1966. Groucho later admitted that is was the first time he had been on a dance floor in 20 years.
