Now he's at it again.
Folk legend Bob Dylan mingled unnoticed with Beatles tourists during a minibus tour to John Lennon's childhood home.
The 67-year-old troubadour paid £16 for the public trip to the 1940s semi in Woolton, Liverpool, last week as his European tour called at the city.
He was one of 14 tourists to examine photos and documents in the National Trust-owned home, where Lennon grew up with his aunt Mimi and uncle George.
A National Trust spokeswoman said Dylan "appeared to enjoy himself".
The trust said its tours of the Beatle's childhood home form "an insight into his humble beginnings".
Visitors are free to wander around the property while asking questions of the curator.
But as tourists prepared to drive out to the house to get an insight into one musical icon, they did not recognise another one sitting next to them.
"He took one of our general minibus tours. People on the minibus did not recognise him apparently," the spokeswoman said.
"He could have booked a private tour but he was happy to go on the bus with everyone else," she added.
The house, called Mendips, has been restored to its original 1940s style by the trust and contains early Lennon memorabilia.

Here's a video from the National Trust the includes the house Dylan visited:
A spokesperson for National Trust, who own and maintain the house, said: "We couldn't believe it when his agent rang us and asked if we could get Bob on one of our tours to see John's house. He spent ages going through photo albums and was thrilled at all the memorabilia."
Here's an audio interview for Rolling Stone
of John Lennon talking about Bob Dylan:
What Dylan and Lennon may actually be
best known for doing together is riding
in the back of a taxi in London in 1966
(which you can see here and here and here)
and having a rather memorable chat.
Here's a video that includes the historic
footage with Dylan's own "Changing of the
Guards." Imagine two major icons just
shooting the breeze in an era long gone:
