101 Gang Songs is an LP recorded in December 1960 by Bing Crosby for his own company, Project Records and distributed by Warner Bros. and the RCA Victor Record Club in 1961 with lyric sheets to help the listener join in with the singing. Spread over two records, the album consists of 24 medleys of 101 old songs in a sing-along format. Bing Crosby sings on most of the tracks. Those that aren't are marked with an asterisk. The chorus and orchestra accompaniment, arranged and conducted by Jack Halloran, was pre-recorded with Crosby over-dubbing his vocals.

"Shine On, Harvest Moon" is a popular early-1900s song credited to the married vaudeville team Nora Bayes and Jack Norworth. It was one of a series of moon-related Tin Pan Alley songs of the era. The song was debuted by Bayes and Norworth in the Ziegfeld Follies of 1908 to great acclaim. It became a pop standard, and continues to be performed and recorded in the 21st century.
