I saw Van Halen on the 1984 tour, there was no extra keyboard player. Ed played some keyboard on the intro into Jump and some in the middle, but stuck with the guitar for the solo. He did a solo keyboard pice as well seperately.
The Van Halen brothers' father, Jan, was a freelance saxophone and clarinet player who performed styles ranging from big band to classical in the Netherlands. The family moved to Pasadena, California in 1967, with 15 dollars and a piano, as Eddie once said.
