I guess I would say in reference to those horrible cover songs, that it is not the least bit extraordinary that the Melodies the Beatles produced spoke to so many types of people both musical and non-musical and across so many different forms and styles of music. The songs the Beatles created struck a nerve and connected with such a vast spectrum of individuals.
On another note, I have observed that younger generations mostly perceive the group as a mere collection of the individual members. A perspective where, not having experienced the group as a whole complete unit for an elongated period of time, it’s a band where Paul McCartney (the dude who recorded with Stevie Wonder and Michael Jackson) + George Harrison (the dude who sang with Tom Petty, Bob Dylan and Roy Orbison and played with Clapton) + Ringo Starr (the dude who has an All-Starr Band and still tours) + John Lennon ( the dude who sang Imagine, married Yoko Ono and got shot) = The Beatles. A hindsight perspective in which this collection of personalities used to simply be a group way back when.
However, our perspective is of the group itself FIRST and the magical, mystical music
they made together that blew our minds out in the car, at home or wherever we happened to be when we heard it. We understand the journey and know when and where it started rather than just looking back at it after the journey has long since been over so to speak. We knew the band as The Beatles before we knew who the individual band members were as opposed to knowing an individual member first and then citing that they were in this band called, The Beatles, in a crazy period of time when a fad known as Beatlemania existed.
I believe this slight difference in perspective transforms one’s attitude, ideology and general impression of the band. When you look back after the fact then pre-conceived notions alter your thoughts and opinions about the original group creating an alternative reality that conflicts with the actuality of what really happened through the eyes of the people that participated in the journey.
I hope this is making sense because I am starting to confuse myself.
So, in conclusion, The Beatles Rock and if the younger folks don’t get it well...then... I hope they find, they change their mind and open up the door.
