Larry Underwood is one of the heroes of the Stephen King Apocalyptic Thriller, The Stand.
He is a cocky, young singer and composer who, at the start of the book, is beginning to get significant success with his first single, "Baby, Can You Dig Your Man?" However, he tallies a debt with a local drug dealer while living in Los Angeles and travels to New York City to hide while visiting his loving, but very disappointed, mom. As the plague and chaos destroy New York, Underwood attempts to care for his dying mother, but he is unable to stop her from dying of the superflu. Pretty soon, Underwood finds that he is one of the few living people remaining in New York City. He meets a troubled, middle-aged woman named Rita Blakemoor and the two decide to leave New York together. They experience a scary expedition through the Lincoln Tunnel while leaving the island, and it is an incident that Underwood is often haunted by in the remainder of the narrative. Blakemoor soon dies from a drug overdose that Underwood concludes as "70% accident and 30% suicide."
