The Doors drummer John Densmore has just added to the value of his autograph after stating he'll never sign his name for a fan again.
The Riders on the Storm hitmaker has taken to his website to kindly ask fans to stop requesting his signature.
He writes, "The last several years I have been so flooded with requests that it is interfering with my personal life, and I am going to have to stop.
"Fans (or opportunists from ebay) track me when I land at any airport, follow me into the bathroom, and hang around my hotel, looking for my John Henry (autograph). It is unfortunate, but I have to draw the line."
Former Beatles star Ringo Starr did a similar thing in 2008, when he posted a video online and pleaded with admirers to stop sending him fanmail and autograph requests.
Starr insisted he would retire his signature and quit responding to mail after 20 October, 2008.
He announced: "This is a serious message to everyone watching my update right now... I want to tell you, please, after the 20th of October, do not send fan mail to any address that you have. Nothing will be signed after the 20th of October. If that has the date on the envelope it's going to be tossed.
"I'm warning you, with peace and love, but I have too much to do, so no more fan mail, thank you, thank you, and no objects to be signed - nothing."
