Gymicrae

If Nathan Maxwell wasn't the first bassist in Jim McCray (same band as gymicrae, also same pronunciation), then who's the guy playing an entire show with Jim in the attached YouTube video? Any why is Nathen mysteriously posing with Jim and Kurt Barlage (their first drummer) in a Jim McCray band photo? Truly a mystery. Also, "gymicrae" is NEVER capitalized. Only lowercase letters.
