I agree with you to an extent. Nothing comes close to the popularity of the Beatles, and no other bands transcend generations the way they do. But I think zeppelin and the Who are two of the most important bands of the 20th century, so it will be nice for young people to get turned on to bands like that, but it was a bad move replacing the Beatles act.
This new act also really has no cohesiveness. The British Invasion really played up the parts, stayed in character, the whole show had a common theme, whether it was Sgt. Pepper-era, or Ed Sullivan days. These new dudes just seem like a bunch of...if I may...Jabronis....rocking out on stage.
Sorry Disney, I try not to complain often, but this was a bad call.
I'll miss the British Invasion!
