The Knack's "My Sharona" spent over a month at the No. 1 spot on the Billboard singles chart in late summer 1979 -- from August 25 to September 29. In that period, the band apparently performed to 900 people at Kirkwood High School, at least according to the book So, Where'd You Go to High School? This Google books link has one line about the concert, but no other details. Were you there? Do you have photos? Stories? I'd love to hear them. Knack singer Doug Fieger, as we reported earlier, died yesterday.
