Music-parody duo Palette-Swap Ninja has transformed every song on the Beatles' album "Sgt. Pepper's Lonely Hearts Club Band" into a Star Wars musical parody. Sing "Princess Leia's Stolen Death Star Plans" to the tune of "Sgt. Pepper's Lonely Heart's Club Band" and you get the idea.

"Our new album merges both into one full-length concept album titled "Princess Leia's Stolen Death Star Plans," singer and guitarist Dan Amrich wrote on the duo's website. "It's the entire Beatles album as accurately as we could record it, only now it tells the story of 'Star Wars: A New Hope' -- in order."

"We sweat the details on both sides in an effort to do both cultural milestones justice," Amrich added. "Writing hyper-specific lyrics that match the original songs' cadences; reverse-engineering everything the Beatles recorded, from distorted saxophone riffs to Indian tabla rhythms; recording everything from scratch and learning as we went."

Listening to the parody, or filk music as we geeks call it, you'll hear some clever parody lyrics. But the real accomplishment is the work that's obviously been put into creating a tribute that both Star Wars and Beatles fans can enjoy.

Personally, I love the lyric swap of "Lucy in the sky with diamonds" replaced with "Luke is in the desert and whining." The album also uses the Beatles song "Lovely Rita" to serenade us about the unwarranted affections of the trash compactor monster in the song "Dianoga."

The new album celebrates the 50th anniversary of "Sgt. Pepper's" and the 40th anniversary of "A New Hope." You can download it for free or listen to it as a playlist on YouTube.
