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.
Funny story about this song...In 1984 Van Halen released their hit album 1984. The first single off of that album was the song Jump. The B-side to that single was a now relatively unknown song, House of Pain. Eight years later, a band named House of Pain made a hit single called Jump Around. For a brief period of time it looked like a blend of edgy rock and hip hop was workable.
