Dear Catters, In my opinion John Lennon was a tremendous song writer. How much of this song ( Because ) had help from Paul and other great creative studio processes , goes without saying. A song is created and embraced/loved by one and all. ( Do you question what influence ( if any ) your own countries National Anthem was created under ? ). Usually not ! Enjoy the song for what it's worth. We all know John Lennon was not a media darling ( or maybe he just told the truth to often ). However, if drugs made him or helped him create that song , than so be it. ( How many songs over the past 100 years in rock, jazz , folk, pop and possibly classical were created or started under the influence ? ) Please understand I have just nursed a younger brother ( the age of 40 ) through a heroin overdose ( where his kidneys shut down ) for the past 3 months and it hasn't changed my love or respect for my brother and/or John Lennon.
