While it's easy to be sceptical, if not downright cynical, about this Beatles' theatrical tribute show - not the first and far from the last - certain things are undeniable: the American cast of this widely acclaimed production deliver an often uncanny musical verisimilitude, the staging is evocative of the ever-changing 60s which the Beatles frequently defined and, not the least, there are some pretty darn good songs showcased.
In fact 40 or so songs in all, and almost all pop classics and object lessons in songcraft.
These days with advance technology Beatles tribute acts can deliver convincingly accurate renditions of songs the original band never could.
Studio constructions like Lucy in the Sky With Diamonds, Strawberry Fields Forever and even the famous orchestral orgasm in A Day in the Life come off as authentic from the group (in changing costumes and wigs) plus synth player and percussionist Daniel A. Weiss barely visible at the back in the last half: "Our very own George Martin" quips Lennon/Tyson Kelly in that identifiable accent.
