Yesterday marked the 34th anniversary of John Lennon's murder by Mark Chapman outside his New York City apartment.
I'm by no means a Lennon or Beatles fanatic - I don't think I heard the majority of their catalogue until I was in university - but I can appreciate the contribution he made to song writing and recording technology.
There was definitely a massive hole left in the music landscape when Lennon died in 1980.
Given my unfamiliarity with the majority of his catalogue, I was typically introduced to his work through the multitude of covers.
One of those was Green Day's 2007 cover of Working Class Hero for a Amnesty International fundraising album. The original debuted in 1970 on Lennon's first post-Beatles solo album John Lennon/Plastic Ono Band.
To see the version that first piqued my interest head to YouTube: http://youtu.be/UPPgeDhGzKY.
