Never Trust a Guitarist...
I was at a gig a while back in a really intimate venue where a musician (one of the most famous players of his instrument in the world but I'll not name him as he's an old mate of my dad's!) said of one of my musical heroes (who he used to play with in a well known band) "Never trust a guitarist that can't write music". I passed it off at the time as the gig was great, but I thought about it after for a lot. Why do you need to be able to write music to be a great guitarist? D
