In 1925, Harrison sold the Rockingham Hotel to his friend George Grigg. Grigg also extended the restaurant on the south side, expanding both the bar and the amount of rooms. The Kent Street side of the building was also altered, resulting in a two-story verandah with a central gable. In addition, eight new bedrooms were added. By 1927, the hotel had 100 rooms. In 1934, Grigg sold the hotel to William Collins and Sons, who operated it as a private residence until 1959. During this time, several changes were made to the property, including the installation of electricity and running water in all rooms. In 1960, the hotel was purchased by J.C. Penney and converted back into a commercial structure. Harrison bought the hotel back from Grigg in 1926. He had been trying to sell it since at least 1920 but was not able to find a buyer until after he sold it to Grigg. Harrison died in 2001 at the age of 58. He is best known for his work with The Beatles.
