He also has a song where he writes about being heckled at Shepherd’s Bush when he played Livingstone Bramble (“I hate Nels Cline”). I was there, he wasn’t heckled, people laughed nervously and someone asked him, quite politely, why he hated Nels. He went on a rant about Wilco (which in the song he reports as ‘I explained that I didn’t hate Nels’ or something).
TL;DR, I’m not sure I trust MK to be 100% accurate with his stories.
