i have. several times under different circumstances (all on the business end of things).
please don't misunderstand my prior post ("while pat has no shortage of arrogance himself, he has the goods to back it up.") to infer that he's an ass or anything of the sort. i simply mean to say what you said in a subsequent post; that a certain amount of arrogance goes with greatness.
sometimes it's difficult for me to determine the line between healthy and unhealthy, again not that i feel pat's is unhealthy.
ps: as a footnote, if you're going to determine whether a musician, or anyone for that matter, is arrogant (or nice or generous or genius or whatever), you're not going to get a good fix on any quality unless you spend some serious time with that person.
