In response to Scrump's fair comment about s/s doing exclusively their own material: I cannot speak for Ron, but for myself, the reason is actually simple: I don't think I am good enough to cover other people's songs on my own, and I won't do it unless I feel I can impart something of myself as a performer, add something. Hence, I very rarely do covers in my sets. I was a "reluctant performer" from the start, doing it just to get (my) songs out and about, to give them a chance to be aired and survive or not according to their worth.

So - not "pride" or "arrogance", but feeling of inadequacy. And before people flock to tell me otherwise (thank you but don't), remember - this is how I see myself, and I am happy with that. For me in this case it's the songs that are important, not the singer.
