You may have seen the boys behind musical group Introducing Fish Taco in their early days, busking on the corner of Calhoun and King as a pair of Charleston cops looked on. Busted for making too much noise and attracting too much of a crowd, Charles Carmody and Dan Hanf have had to move their act to bigger and better venues, playing their particular brand of folksy, acoustic improv and parody for the crowds at Awendaw Green, the Music Farm, the Green Fair, and a past Charleston Comedy Festival. With a brand-new lineup of original songs, the duo takes the stage at Charleston’s PURE Theatre with Introducing Fish Taco: The Musical, the epic adventure of brothers Kellogg and General Mills, creators of the cereal demi-gods at the beginning of time who come to blows over their mutual love for Little Debbie. “Then we get back to the present day with our main character Pete Reynolds,” Carmody explains. “He discovers he has run out of his delicious Lucky Charms and is forced to set off on a quest, only to find himself in the middle of the long-standing cereal feud.” Doors open at 7 p.m. for an hour of drinks, free salty snacks, and lobby entertainment before the musical tragicomedy begins at 8 p.m. “Dan and I will be outside on the sidewalk for the hour before, harassing people with our music to come on in, so it’ll be a good time,” Carmody says. The first 10 people through the door get a free handmade T-shirt.
