TWINE frontman Will Effertz did know California Honeydrops’ music but didn’t know saxophonist Janos “Johnny Bones” Lustig when he approached the stage at Bunker’s last Wednesday night. “I have had that happen in instances, and when it’s a saxophone, I am like, ‘Please, be good.’ It turned out he was a badass.” Read more about the unplanned sit-in from Lustig on a night when local vocalist/guitarist Joe Dunn and sound man Gage Schmitt (on flute) were already featured.
