Keith Richards only communicates by fax.

The 67-year-old Rolling Stones rocker favours sending notes through a telephone line, much to the amusement of his bandmate Ronnie Wood - who struggles to intercept the guitarist's messages.

Ronnie explained: "Keith, he still communicates through fax, no other way but a fax.

"That's why I never hear much from him because I ain't got a fax machine.

"It's fantastic, you get a message from Keith on a fax. You get 'I don't know when, I don't know where, just get ready. Love, Keith'. It means we may be touring sometimes in the next decade, I don't know."

However, though Keith has struggled to get to grips with modern technology, Ronnie is impressed by his former Faces bandmate Rod Stewart's ability to embrace new ways of communicating.

Ronnie said: "I have had various emails, because Rod is getting very, very good on the emails, we've been doing to and fros lately, with sort of 'How you doing, mate?', you know, Blah Blah Blah.

"Who'd have thought that. Rod, I mean, it's like he was never any good on the telephone - let alone the laptop. "

Ronnie, 63, is a huge fan of technology and even carries around spare mobile phones in case his main communication device fails.

He admitted to Absolute Radio DJ Christian O'Connell: "I don't have an iPod. have lots of. actually I've only got a three gigabyte phone or something, I can't get enough music on mine.

"I do have about three old Nokias that sort of operate without a sim card, you know, it's fantastic, I just swap the sim card in various areas. I've got my iPhone, which is my main thing, and lots of spares.

"You can get me on Twitter too."

Ronnie now has a daily radio show on Absolute Classic Rock at 4pm Monday - Thursday and 6pm on Fridays.
