It has been said that all modern (post-mid-sixties) rock is derivative of the Beatles. The Beatles, in turn, freely acknowledged their debt to the Everly Brothers in terms or their vocal arrangements and harmonies. Anyone who has listened to old Everly Brothers and old Louvin Brothers recordings can notice that the Everlys derived a lot of their duet techniques from the Louvins.

Ira Louvin is deceased, and not available for punishment.

Therefore: Charlie Louvin is to blame for modern rock.

Let's Git 'im!

Peter.
