Van Halen's most successful and best-known hit single of the David Lee Roth era was undoubtedly "Jump," off their classic 1984 album. Although the single was a number one smash (staying at the top of the charts for five weeks), the song had been kicking around for several years unused -- it's rumored to have been written around the time of 1980's Women and Children First. Although it wasn't Van Halen's very first song to incorporate synthesizers/keyboards into their heavy rock sound (such tracks as "And the Cradle Will Rock," "One Foot Out the Door," and "Dancing in the Streets" already had), singer David Lee Roth felt that Eddie Van Halen should concentrate more on the guitar rather than keys. But Eddie was upset with the direction of their previous album, Diver Down (which was heavy on cover songs), and made it a point to put his foot down on 1984. It definitely helped that he had built his own recording studio, 5150, and when the others asked what he had up his sleeve for the new album, he said that the "keyboard thing was all he had left." The rest of the band obliged. It's rumored that David Lee Roth came up with the title after seeing TV news footage of a man attempting to commit suicide by leaping off a building, as bystanders were goading him to "jump." Both "Jump" and 1984 are rightfully considered by many to be among the '80s top rock accomplishments.
