Bob Dylan and Paul McCartney have known each other for over four decades. In 1964, Dylan and The Beatles first met in New York, and the famous story goes that Bob introduced them to pot. Over the years, Dylan became friends with George Harrison, playing the Concert for Bangladesh, writing “I'd Have You Anytime,” with him, and of course, playing with The Travelling Willburys. In recent interviews, Dylan expressed his admiration for McCartney’s talents and McCartney in turn said that working with Dylan was one of his major ambitions. That's as far as it's gotten, no plans have been made, but there is a good degree of speculation about the possible musical merger.

Neither McCartney nor Dylan have let any dust settle on their careers – both have been creatively active. Dylan tours constantly, and McCartney is taking himself and band around the Northeast this summer. Dylan’s latest CD, Together Through Life, reached number one on the US and UK charts. McCartney’s Memory Almost Full went to #3 on the Billboard charts, and both CD’s received high praise in their reviews. McCartney has also released a CD in collaboration with Youth, original songs of ambient music with vocals, called The Fireman. Pretty edgy stuff for someone past 64, a testament to McCartney's creative wellspring.
McCartney and Dylan are at opposite ends of the spectrum when it comes to songwriting style – McCartney is a genius of memorable melody and Dylan is known for setting his lyric genius in established roots music song structures. Both men obviously admire each other, though, and it would be fascinating to see what would occur if these two giants of modern music got together to create.
Whether a collaboration pans out or not remains to be seen. That Dylan and McCartney could be considering it is enticing news to all of their fans. If enough fans are asking for it after hearing the speculation, who knows? Maybe Bob and Paul will shrug and say, "What the heck." Stranger things have happened.
