RCA did not actively promote "Rhymes & Reasons" with a tour, but Denver embarked on an impromptu supporting tour throughout the Midwest, stopping at towns and cities as the fashion took him, offering to play free concerts at local venues. When he was successful in persuading a school, college, American Legion hall, or coffeehouse to let him play, he distributed posters in the town and usually showed up at the local radio station, guitar in hand, offering himself for an interview. With his foot in the door as writer of "Leaving on a Jet Plane", he was often successful in gaining some promotional airtime, usually featuring one or two songs performed live. Some venues let him play for the "door"; others restricted him to selling copies of the album at intermission and after the show. After several months of this constant low-key touring schedule, he had sold enough albums to persuade RCA to take a chance on extending his recording contract. He had also built a sizable and solid fan base, many of whom remained loyal throughout his career.
