The Andrews Sisters once again eager to be a soloist. In 1969, Patty appeared in Lucille Ball's third series "Here's Lucy", in the sixth episode of the second season, titled "Lucy and the Andrews Sisters". The episode has Patty enlisting the help of Lucy, her daughter Kim (played by Lucie Arnaz), and her son Craig (Desi Arnaz Jr.) to perform a medley of Andrews Sisters hits for the Andrews Sisters Fan Club reunion. Lucy played LaVerne, Kim (Lucie Arnaz) played Maxene, and Craig (Desi Arnaz, Jr.) played Bing Crosby. She also had a cameo as herself along with many other stars in the
Don't Sit Under the Apple Tree (with Anyone Else but Me) the "Billboard" charts and was ranked as the nation's twelfth best-selling recording of the year. In May the song was featured in the film "Private Buckaroo" as a performance by the Andrews Sisters with the Harry James orchestra and featuring a tap dancing routine by The Jivin' Jacks and Jills. This scene is often considered one of the most memorable of the film. The Andrews Sisters then released the song on Decca Records. (In a 1971 interview, Patty Andrews reported that this was their most requested song.) Many other artists released records of the song that year, including Kay Kyser.
