These guys are as close to the real Beatles as possible. Very good musicians and singers, playing what appeared to me the same instruments as the Beatles did in the 60's. I was really impressed with "George and Ringo's" parts, as they played guitar and drums exactly as they were played on the records.
They sing well, harmonies are good. They were willing to take on some hard songs like "Strawberry Fields Forever" with the additional keyboard player, and did them well. Note the songs from 1967 to 1969 were never played in concert, as Beatles stopped touring in 1966, so it was nice to hear. The fact they are from Liverpool lends authenticity to their accents and conversation to the audience. It felt like a great concert, with graphics on screen too. If you are a fan of the Beatles music, see the Mersey Beatles, you will love them.
