Bo Diddley is so cool he can play songs with his name in the title.
"Bo! Awesome song! What'cha gonna call it?"
"Don't ya think that's a little-"
"Don't question Bo Diddley! If Bo Diddley says the name of the song is Bo Diddley, then the name of the song is Bo Diddley!"
Seriously. There's the self titled track, Bo Diddley, then there's Hey Bo Diddley, The Story of Bo Diddley, Bo Diddley is Loose, Bo Diddley's Hootnanny... he even has a song called Bo Diddleys Dog. Then there's Bo's Blues, Bo's Guitar, Bo's Twist, Bo's Waltz... and my personal favorite title: Bo's a Lumber Jack. Yeah, seems like he was stretching at that point.
"Bo Diddley's gonna play a new song. It's a song about Bo Diddley. It's called 'Bo Diddley put the Rock in Rock N Roll'"
"Bo, it's kind of presumptuous to-"
"Quiet! Bo Diddley did put the rock in rock N roll! Now you best settle down before Bo Diddley takes it back out!"
He did, however write the classic blues song I'm A Man, so thanks for that one! I'm thinking the reason most of his songs were written about himself is ... well... check some of his other titles: You Ugly, Cookie Headed Diddley... and... I'll Lick Yo Face. Yes I'm serious about that one.
"You'll lick my what?!"
"Bo Diddley will lick yo face! Don't make Bo Diddley do it!"
"Bo, Bo... calm down!"
"Do you want Bo Diddley to lick yo face?! Bo Diddley swears he'll do it!"
I don't know why Bo Diddley becomes Ike Turner in my head ;)
