We talked to the father and son-led team about how this magical music mystery tour came into being and what audiences have in store.

They are rightfully regarded as the most influential band of all time, but The Beatles did most of their pioneering work in the studio.

By the time the groundbreaking Sgt Pepper's Lonely Hearts Club Band came out in 1967, they had packed away their touring gear for good.

But in a unique collaboration between George Hastings, the music director of the SoundPower Orchestra (SPO), and tribute band These Beatles – fronted by his son Adam – audiences at the Customs House, will experience just how the Fab Four's later, more experimental, work would have sounded live.

Though from different generations, the father and son duo both wanted The Beatles' songs to be played as authentically as possible, as George explained.

"The talent in the Beatles was phenomenal, and like Mozart and Beethoven they will never be forgotten.

"While we were thinking of ideas for shows for the Customs House, where the SPO is resident, somebody came up with the idea of a Beatles night and I thought this was a great opportunity to hear Adam's tribute band.

"I then sat down with them, and we thought of all the things we could do with an orchestra.

"I've been a musician for a long time and it takes a lot to impress me, but I was knocked out by all the lads. I could have been watching the real Beatles.

"Some of the tribute Beatles bands are getting on a bit, so these are much younger ones.

"Their standard of music is so high, they have the technical ability to reproduce all the little licks the original Beatles had."

This pride in reproducing an authentic Beatles experience is something which Adam, 21, a student at Leeds College of Music – and John Lennon in the band – also takes very seriously.

"We hope the audience will lose themselves in the music and forget it's not the original Beatles they're listening to," he said.

"We've spent hours painstakingly reproducing every chord, note, vocal nuance and mannerism of John, Paul, George and Ringo.

"We don't just sing the songs; we become The Beatles for the evening. Even our banter in between numbers stays in character."

While the first half is more like a traditional tribute gig, with performances of such hits as Love Me Do, I Wanna Hold Your Hand and Paperback Writer, the second, incorporating the 35-strong orchestra, is much more ambitious.

Together they go on to perform hits such as Hey Jude and Strawberry Fields Forever.

Adam added: "In the second half, the powerful sound of the full orchestra is phenomenal."

Just like some books cannot be made into films, many critics said later Beatles material couldn't be reproduced on stage, but George believes he has proven them wrong.

"I've reproduced the George Martin original orchestrations, such as the backing strings on Yesterday.

"By listening to them, I can hear what was an original string quartet and we play it with a much larger orchestra," he explained.

When asked why he'd attempted such a task, the music evangelist part of George, who has fought for years to get rid of classical music's stuffy image, made itself apparent.
