Went to a concert at the local theatre (Monday night concert series) called "Rave On". Featured the music of the various artists; the same performer played the music of Dion and Richie Valens, another did Buddy Holly and a third did the Big Bopper (he was closer in age to what the Big Bopper would be now than what he was then, but they were not pretending to be them, only to cover them). Really good show.
The fellow who did Richie Valens was the hit of the show, particularly with his rendition of La Bamba and also a mariachi "tribute" he played on his guitar. Got him a standing ovation.
