Sammy Hagar, lead singer for Van Halen, during a Sept. 30, 1988 concert at Rupp Arena. Hagar took over lead vocal chores for Van Halen after David Lee Roth left the band in late 1985. At the time of the concert, the group’s single, When It’s Love, was among the top 10 songs on the Billboard magazine charts. The Rupp concert was the opening show of Van Halen’s fall concert tour, and tickets were $16.50. During the show, Hagar wasn’t above dissing the band’s road crew, including at the end of Where Eagles Fly, a track from Hagar’s 1987 self-titled solo album. What do you do when you’ve just performed an entire song with an out-of-tune guitar? Simple: You get the entire audience of 13,000 to boo the roadie who tuned it, which is what Hagar did.
