I quote from the Barbican Press Release
"For over thirty of those years (!!!) they have been performing these ‘classic’ pop songs to audiences across the
globe, winning over even the most hardened sceptics with their stunning
recreation of The Beatles’ sound and look. With a little help from
their orchestral ensemble, they even manage to reproduce live on stage
songs The Fab Four never actually performed themselves. Every tiny
detail is meticulously covered from costumes to authentic period
instruments; from their witty ‘Scouse’ banter to their ‘inflection
perfect’ vocal mimicry. They are now booked to play the main stage at the Glastonbury festival in the summer of 2013. Tickets are on sale now, priced £26.50."
I must admit they are excellent at putting on a good show, it's highly polished now and is the closest a Beatle fan will ever come to seeing a 'live' almost Beatles performance. I saw them way back in the 1980's, they were a little thinner then and only played as a foursome, now they have expanded into a bit of a variety show complete with orchestra for those 'Let it Be/Winding Road' numbers (although I would have thought McCartney would prefer no strings). Here are some pix of them, they look and sound authentic, but its amazing with the electronic wizardry now and backing tracks how you can mimic any rock group. Still, it's all we have.....
PS - My one criticism is that the 'McCartney' unashamedly plays his instrument right handed, - now call me finicky but it is a major and dynamic Beatle fact...
