It was 50 years ago next week that The Beatles released what is widely considered one of the best and most influential albums in rock n' roll history - Sgt. Pepper's Lonely Hearts Club Band. From its cover to its 13 tracks, the album was full of firsts with many popular songs, like "With A Little Help From My Friends," "Lucy In The Sky With Diamonds," and "A Day In The Life," as well as lesser-known gems like "Lovely Rita" and "Getting Better." To commemorate the anniversary, Universal Music Group and The Beatles record label, Apple, have released a boxed set that includes a remix of the album, outtakes and alternative tracks, and documentary on the making of the album that is also scheduled to be aired on PBS stations. Music historian Anthony DeCurtis, who writes for Rolling Stone magazine, spoke to Alison Stewart about the famous album.
