An 82-year-old man broke down in tears after losing his most prized possession at the Cavern Club.
Stan Cargill, from Halewood, took his lifelong collection of Beatles memorabilia to the venue on Monday when he accidentally dropped it.
It was initially believed the book, which "means the world" to Stan, had been stolen after a CCTV image of a man was shared widely on social media.

However, the Cavern Club has now set the record straight after the book was today returned to the venue by a man who found it on the stairs.
Bill Heckle, who owns the Cavern Club, told the ECHO the man was rushing for his train home to Sheffield when he came across Stan's book and asked the people in front of him if it was theirs, which it wasn't.
The man said he didn't realise how important the book was at the time, and it was only the next day when he looked at it with his girlfriend that he realised just how sentimental it was.
After seeing a photo of himself shared widely on social media, the man got in touch with the person who created the post and arranged to return it to the Cavern Club today
The Beatles book has signatures from Paul McCartney and Yoko Ono, an original Cavern Club membership card and photos of him and the Beatles from when they were teenagers inside.
The ECHO understands Stan is now on his way to collect it from the Cavern Club after it was returned this afternoon.
Stan's niece, Steph Cargill, 30, told the ECHO: "He's just been really upset. I don't think he's slept much last night.
"As I say, he constantly has it with him. He doesn't take it out of his pocket.
"He's basically made it from a photo album and he's filled every single page in it with signatures and original photographs. He's got a letter off Paul McCartney - he's actually met Yoko Ono and Paul McCartney.
"It means the world to him."
Steph and her family would like to thank everyone who helped by appealing for information on social media and leaving their well wishes in the comments.
She said: "I don't even think there's enough words out there to thank them. Obviously there's good people in the world and a lot of them come from Liverpool.
"The whole family was devastated. It broke our hearts because we know how much the book means to him."
