That's hysterical -- they pretty much exposed the entire rock audience to that sound on both guitar and bass. McCartney's lefty Ric was custom made for him and basically a gift, and it is HUGE and all over Sgt. Pepper, which is of course one of the most influential recordings made in the first generation of rock.
Edited to add: of course, I must weigh in with my Ric history: bought from the delightfully-named Wedgle's Music and Loan in Denver, CO, circa 1987 as a graduation present. I can't remember how the heck I figured out the year, because I knew it before I had access to the Internet, so someone (like, a live person) must have told me. It's a 1973 as evidenced by the MA prefix of the serial number. Crenellated binding, little tiny pewter Grover tuning heads (fell apart, replaced with Schallers in 1991 or so). The foam mute was collapsed and useless (and has no knobs) before I ever got hold of it, and I have to drop a little piece of pencil lead or sometimes plastic into the nut slots because otherwise the string rides too close to the board. I should replace the nut someday. Also, I've noticed my neck pickup is almost SITTING THE **** ON TOP of the neck, which makes it extremely boomy. It has a very slim neck (unlike many 1980's-era 4003s) and plays like a dream.
I get twitchy taking it out, and pretty much I only play it at my "home" bar, the Bluegrass Brewing Co in Louisville. Anywhere else, I take a different bass.
