The Eugene Concert Choir decided, in an effort to promote their upcoming “British Invasion” concert of Brit-influenced choral music, that it would be fun and entertaining to recreate the iconic cover of the Beatles’ 1967 Sgt. Pepper album.

It turned out to be a lot more work than anyone realized — and a whole lot of fun. They even got the mayor to join in.
