It really was just by chance. There is an outdoor area with lots of picnic tables at this particular venue (The White Rabbit in San Antonio). I saw him at a table and I recognized his face. I went up to him and said "Moe Blunts?". He was kind of astonished. Then I said "I'm timedragon". He bursted out with enthusiasm and friendliness. We hung out for a while, there. Cool fellow.

The concert was with Ensiferum, Finntroll, Eluveitie and Tyr, if I remember correctly.
