Here is a video I saw on BB-Blog with backstory on “A Day in the Life,” included on the Sgt. Pepper album, released in 1967. It is considered by many to be the most influential rock song ever, containing two portions independently composed by Lennon and McCartney which are joined by an orchestral bridge. The famous E-major chord at the end was played simultaneously on three pianos and rings out for over forty seconds.

Have a great Sunday, and celebrate the Beatles!
