I could understand people arguing against Harrison's guitar-playing talent (mostly music fans of the Rush variety). He's no virtuoso, he doesn't play "hard," he doesn't play fast and wild BUT his style and his playing is VERY distinguishable, meaning you can hear a lick, a riff or a solo, even if it's not a Beatles song, and know right away that Harrison had something to do with it.
When I was in college--with no context--I was listening to the Badfinger song "Day After Day" and noted that the guitar stylings sounded like a distinct pairing of "Badge" and "Something." Then I learned Harrison played on "Badge" (Cream) and had a heavy hand in writing/producing "Day After Day."
Never has my musical ear been more validated!
Upfront? So...candid?
