How much time do you spend playing songs you'll never perform?

[Nicko]

Almost none on the bass, cos I'm lazy and don't practice much in any case. I pick up the bass for learning new stuff for the band (covers) and every now and then when by creative juices get flowing. My originals will likely never be played cos the band doesn't seem interested in originals. I play quite a lot of guitar stuff but don't have any intention of ever being a guitarist in a band.

Loads, because the knowledge and techniques contained within can be worth more than the value of playing it live (to me, anyway)

It's funny when you're on a site like YouTube to see where you end up - which is usually a million miles away from the song you originally started on. All good stuff though, as you said.
