The photographer will depict what 60s Liverpool life had to offer - other than The Beatles - when his exhibition of black and white pictures opens next month.
The exhibition will be launched before Sir Paul plays to 40,000 fans at the King's Dock on Sunday, June 1.
Mike, of Heswall, still refers to his billionaire brother as 'our kid' and said it was not out of character for him to eat chips in Chester Cathedral's grounds rather than living it up at the Grosvenor.
Fans are currently getting a taste of Mike's photography on the UK leg of his brother's world tour. In fact, Mike was name-checked at the MEN Arena last Thursday last week.
Macca, 60, told fans his brother provided him with rare Beatles photographs, which are shown on a video wall during his tribute to George Harrison, an acoustic version of Something.
But Mike has chosen to ignore the Fab Four in his forthcoming exhibition.
'I saw a film of our kid's US tour and asked if he wanted some of my pictures and he agreed,' he said. 'But in the exhibition, our kid does not get a mention. The pictures are all black and white but there will be no Beatles.'
In fact, the only picture relating to The Beatles is a picture of George Harrison's Jaguar as well as Mike's first motor, which he describes as a 'classic'.
During the 60s, Mike had access to the most happening and interesting people around. But he had no idea he was photographing the era that changed music history.
This exhibition is an entertaining mix of snapshots of stars and everyday Liverpool life, from pictures of his dad at home to the kings of rock 'n' roll such as Jerry Lee Lewis and Little Richard.
It also features candid pics of Mike's former band, Scaffold, who enjoyed a Number 1 hit with Lily the Pink in 1968.
'There was much more going on at that time than The Beatles,' said Mike.
Other pictures in Mike's exhibition include poet Roger McGough - also a former Scaffold member - asleep on a train and a young Lewis Collins working in a Liverpool hairdresser's.
As well as photography, Mike has recorded nine albums, both as a solo artist and with such names as Elton John, Jimi Hendrix, Spencer Davis and Wings.
* Mike McCartney's Liverpool Life will run at the Museum of Liverpool Life, Pier Head, Liverpool from Thursday, May 29, until September 28. Free admission. Open daily 10am-5pm.
