So... back in the eighties my Dad was battling alcoholism. He went into rehab and after a week he was allowed to call and talk to us. I'm on the phone with him and he says "I have this English roommate. I think he plays the guitar, his name is Eric something."I did... but it was early 80's and he was a coked out mess... It was pretty sad.
Long story short, yes, his roommate was Eric Clapton and on at least one occasion Eric picked up his acoustic guitar and asked my Dad if he'd like to hear a song. My Dad was privately serenaded by Eric Clapton in their "dorm" room in rehab singing "Dear Prudence". My Dad was captivated. I think it was refreshing to Eric that my Dad had no idea who he was. He called my Dad "that short little Irish bast*** from Boston".
Good news is that my Dad remained sober after that experience for the rest of his life. I can't speak for Mr. Clapton.
