how is there "a bit of truth" in that horrible statement? If this is an average thing for him to say, that doesn't make it any better... just the opposite.
I don't like "change the world," either, but EC has a lengthy list of mind-blowing recordings, Cream, Derek & the Dominos, solo, and various other contributions. These cannot be "undone" by any number of bad songs. He is a world class musician and songwriter, an absolute legend for the ages. Clapton is still God. His legacy is beyond dispute.
This other guy is just some asshole.
