Indeed. Very American - massive self justification, anything rather than simply admit one is wrong or has made a mistake. I played in a band with s similar fellow from across the pond once. He was a nightmare; he actually told me on one occasion "I NEVER make mistakes". Needless to say, I didn't hang around for long. His wife, who was/is a good musician (she played keys and sang), used to carry him - nodding cues at him, counting him in for breaks, etc, etc. Sometimes, he didn't even tune his guitar before we started playing. If you reminded him, he'd act all insulted.
