When
Sally Flynn left to pursue a solo career in 1972, Sandi wasn't sure about her future on the show since the program already had plenty of soloists. However, she found even greater popularity by being part of a new musical act, a girl group featuring fellow Welk stars
Gail Farrell and Mary Lou Metzger that sang numbers made famous by
The Andrews Sisters,
McGuire Sisters and other famous acts. The trio, with its blend of good looks and pretty voices, also became very popular with fans of the show. In addition, she sang a few solos, toured with the Musical Family in
concerts, branched outside the organization by providing background vocals for numerous artists, and appeared in several television commercials. == Personal life ==
