This sounds like a great event in Portland! I’m sorry I wasn’t able to attend it!
OregonLive.com reported on this event:
Thursday night rush hour in downtown Portland came with its own rock ‘n’ roll soundtrack at the corner of Southwest 4th Avenue and Southwest Jefferson Street.
Hundreds gathered on the steps of Portland City Hall to belt out “Louie Louie” in unison to pay tribute to the hit song and help roll out a summer fundraising campaign.
“Louie Louie” was written by Richard Berry in 1955, but it’s most known for the version recorded by Portland-based band, The Kingsmen, in 1963. Recorded in a studio at Southwest 13th Avenue and West Burnside Street, the song went on to be a classic and at one point, was even investigated by the FBI for alleged inappropriate lyrics.
More than 50 years later, the surviving members of The Kingsmen, along with an adult marching band and an all-girls rock ‘n’ roll band lead what the group claims to be the “world’s largest Louie Louie sing-a-long.” There was even a specially-made “Bluie Louie doughnut” by Voodoo Doughnut for the cause.
