I think my original reasons for playing bass are kind of lame compared to others.
In 1965 a buddy and I decided to teach each other guitar (yeah,the buddy method). And, like others of the era, we'd get together with anyone who'd want to play.
As was common at the time, we'd always end up with a singer, maybe a drummer, and a bunch of guitarists. At one of our get togethers one guys brother says 'you need a bass player'..a what ?
He pulled out a Jazz bass..so I said I'd give it try. No one else wanted to come near it..like it was infected or something. Funny, at the time I was the smallest guy there, that Jazz bass looked gargantuan in front of me. That was in early '67.
In late Oct of '68 I got into my first 'good' band, played top 40 hits of the day. I got in because the bass player got drafted. We'd played regularly, learned alot, and had alot of fun. By then I'd saved up and bought a Hofner, a Vox T-60, and a Vox AC-100 head. I really wasn't aware then that that was the setup McCartney used..I was hot spit huh. The AC-100 was needed to keep up with the Super Beatles everyone else was using.
About 18 months later, I was the only one left, everyone else got drafted..I was the youngest of the bunch.
After the demise of that band I discovered Yes, ELP, Genesis, and the like, and went thru a succession of groups, very creative time.
Around 1974 I was asked to join a lounge act. Now wouldn't you know it, this was my highest paying gig (and I needed the money), but the worst sounding group. It was common place for us to do an intro in C and have the singer come in in F#, this guy couldn't carry a tune in a bag ! But hey, he paid us.
After about 2 years, the singer (who's band it was), mercifully decided to get out of the music business and bought a motel in El Paso. (My condolences to the great state of Texas)
Through all the trails and tribulations, I just can't picture not having a bass around.
Now days I sub for some friends when they need it, some local theater stuff when available, benefits now n then.
But I still manage to play just about everyday, even if it's only scales to keep my hand in shape.
Just can't see it being any other way.
