Right. He'd do the jumps off the drum riser, karate kicks and such. He was the quintessential 80's rock star on stage and back stage.
They made Diver Down in 1982 and it was their shortest album with 5 covers out of 12 songs. A lot of people felt it was a lame effort to moneygrab on their popularity. They then took a longer time than they had to get 1984 done. Apparently Eddie was hyperfocused on getting it musically where he wanted it and I think that album clearly was what caused more rift.
DLR had a "Dave TV" weekend on MTV and came out with his "Just a Gigolo" and "California Girls" mini-LP and it disintegrated from there. They just wanted different things.
"1984 (the instrumental)" and "Jump" were already developed in time for
Diver Down. Van Halen had also composed another synth arrangement, which Ted Templeman turned into the "Dancing in the Streets" cover. At the end of the day, both Templeman and DLR didn't want
their guitar god playing anything but guitar.
There is another story where Templeman tried to replace DLR (rumored with Sammy Hagar, of all people) in 1977, but warmed up to him during the recording of
Ain't talkin' 'bout Love. Interesting that they teamed up years later against Van Halen's musicianship.
It is rumored also that DLR was put off by Eddie marriage to Valerie Bertenelli, because it interfered with the band's party/booze all night image. Basically, Van Halen was maturing and wasn't going to compromise on
1984. Both "Dancing in the Streets" and
1984 seemed to contribute to the first break up.
