Patty continually distanced herself from Maxene, until her death, and would not explain her motives regarding the separation. Maxene appealed to Patty for a reunion, personally if not professionally, both in public and in private, but to no avail. Maxene suffered a serious heart attack while performing in Illinois in 1982 and underwent quadruple bypass surgery, from which she successfully recovered. Patty visited her sister while she was hospitalized. Now sometimes appearing as "Patti" (but still signing autographs as "Patty"), she re-emerged in the late 1970s as a regular panelist on "The Gong Show". Maxene had a successful comeback as a cabaret soloist in 1979 and toured worldwide for the next 15 years, recording a solo album in 1985 entitled "Maxene: An Andrews Sister" for Bainbridge Records. Patty started her own solo act in 1980, but did not receive the critical acclaim her sister had for her performances, even though Patty was considered to be the "star" of the group for years. The critics' major complaint was that Patty's show concentrated too much on Andrews Sisters material, which did not allow Patty's own talents as an expressive and bluesy vocalist to shine through.
