Chuck Berry & Julian Lennon at Berry's 60th anniversary

In February 1972, John Lennon and Yoko Ono took over The Mike Douglas Show for a full week jam with unusual guests including Ralph Nader, Jerry Rubin and Surgeon General Dr. Jesse Steinfeld. But most important guest appearance was by one of Lennon's biggest heroes, Chuck Berry. Berry and Lennon even performed Berry's "Johnny B. Goode" and "Memphis, Tennessee" with Lennon's backing band, Elephant's Memory.
In 1986 during Chuck Berry's 60th birthday concert, Hail! Hail! Rock 'N' Roll, Lennon's son Julian joined Chuck onstage to perform "Johnny Be Goode", same song that Lennon had played with Berry 14 years ago.
