The music legend wasn’t spotted by fellow visitors as he joined a £16 excursion to the late Beatles star’s childhood house.
The Like A Rolling Stone singer was in Liverpool as part of his current world tour and a spokesperson for National Trust – who own and maintain the modest semi-detached property admitted the organisation was stunned to be asked to accommodate him.
The representative 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 all the memorabilia. He’s definitely the biggest celebrity we’ve ever had on our tours. But incredibly no one else recognised him.”
According to sources, Dylan said the 1940s home Lennon shared with his aunt Mimi and uncle George was similar to his own “modest” upbringing.
He was said to be particularly “enthralled” by the musician’s bedroom, where he wrote many early Beatles hits.
Dylan who was a member of supergroup the Travelling Wilburys along with late Beatle George Harrison, Roy Orbison, Tom Petty and Electric Light Orchestra star Jeff Lynne in the 1980s – recently revealed he wants to duet with John’s former songwriting partner Sir Paul McCartney.
The 68-year-old musician said: "That would be exciting to do something with Paul. But you know your paths have to cross for something like that to make sense."
Friends say 66-year-old Paul - who has previously worked with Michael Jackson, Stevie Wonder and Elvis Costello and recently declared the folk star his favourite living songwriter - would love to take up the offer.
A source said: "This would obviously be a major moment in musical history if Bob and Paul got together and it's quite likely that Paul will be interested."
