I think this is all a realization of the influence that Chuck Berry had on a specific form of guitar based rock and roll songwriting. Even more than Elvis or Buddy Holly Chuck demonstrated that having a guitar and playing could be fun. Hell, he still does (when he’s not in jail…which seems to be concommitant with the ‘fun’ aspect).
There’s Blue Öyster’s Cult’s The Marshall Plan from their album Cultosaurus Erectus, which had Don Kirshner announcing “with over a million albums to his name in just 2 short years, my friends, here’s Johnny!”
Then there’s “Johnny, Angry Johnny, this is Jezebel in Hell
I wanna kill you, I wanna blow you…away” by Poe. I doubt if there’s any Johnny B Goode reference there, though.
A local singer, Vendetta Cream, covers an old song called, “Johnny, tu n’est pas un ange,” in her act. But since the song is in French, I don’t know whether Johnny’s a musician. I only know he’s not an angel.
In the case of “I Walk the Line (Revisited)”, the answer is yes. Recorded by Rodney Crowell (ex-husband of Johnny Cash’s daughter Rosanne), the song recalls the first time Crowell “heard Johnnny Cash sing ‘I Walk the Line’”. By clicking the link below, you can read about an amusing anecdote about Rodney’s attempt to suggest that the “Man in Black” sing the classic tune to a new melody:
When Johnny comes marching home again, hurrah hurrah…
When Johnny comes marching home again, hurrah hurrah…
The ___ will sing, the boys will shout, the ladies they will all turn out…
And we’ll all be happy when Johnny comes marching home.
Yes, of course Johnny Angel. I mean, obviously. But also there’s:
Johnny Get Angry – Joanie Summers
Johnny Get Your Gun – George M. Cohan
Johnny Freedom – Johnny Horton
Johnny Reb – Johnny Horton
Johnny, Johnny, Johnny – Kay Cee Jones
Oh, Johnny – Ella Fitzgerald (among others)
Frankie and Johnny – Traditional
Johnny One-Note – Ella Fitzgerald
Many other songs mention a Johnny:
The White Cliffs of Dover – Traditional
I Know Where I’m Going – The Weavers
It’s My Party – Leslie Gore
It’s not the only generic male name, but it seems to have a strong resonance in all kinds of contexts.
