Obviously Sotheby's wouldn't be lending their good name to the sale of the original hand-written lyrics for "Like A Rolling Stone" if they hadn't checked the provenance. They apparently come from somebody in California who was given them by Dylan many years ago and is now looking to cash in. The auction is on June 24th if you're interested. They expect it to fetch half a million dollars.
Just imagine for a second you're a sixties legend and somebody asks if you've got the original piece of paper where you first scribbled the words to your legendary hit. I'd be tempted to say nothing for a few months and then say "you'll never guess what fluttered out of an old book the other day - there it is on the actual hotel stationery with authentic Maxwell House coffee mug mark in the corner. What about that then? Do you think it's worth anything?"
Rock heirlooms seem to multiply according to demand. When I spent some time filming in Memphis many years ago I found that there were as many original recording consoles on which Booker T & The MGs allegedly recorded "Green Onions" as you might find fragments of the true cross in a Tuscan hill town.
Wouldn't mind betting a lot of hit songs never had the words written down properly, not in a form that you or I could read. In the days of Smash Hits you'd often negotiate a fee with the publishers to reproduce the lyrics and then find that they expected you to get the words from the record because they didn't have an official copy of them.
I was amused to see that when they asked McCartney to contribute a hand-written lyric to a charity auction in 2010 he came up with this.
