Sandi Griffiths
American singer
Sandi Griffiths (born Sandi Jensen on August 1, 1946) is an American singer. She is best known as a performer on American television's The Lawrence Welk Show.
Early years
A native of the San Fernando Valley in Los Angeles, California; she started singing as a child and by the age of five, was a regular on TV by appearing on the Art Linkletter program, House Party. She continued to perfect her music skills all throughout school, and in college, at Brigham Young University where she teamed with and became friends with Sally Flynn.
Sandi and Sally
At BYU, the duo sang at the school's musical revue known as the Program Bureau, later at Disneyland and then went over to Vietnam to entertain the troops as part of a USO tour. After three weeks, she and Sally returned to the states to concentrate on their professional careers, in which their break came when they were asked to open for Jack Jones at Harrah's in Lake Tahoe.
It was here that Lawrence Welk and his music makers in the summer of 1967 played their annual three-week engagement at Harrah's.
Gail, Sandi and Mary Lou
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.

Why this record matters
The phrase “american singer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Mar 22, 2026. The linked authority identifier is Q7416311. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1946, 1967 and 1972.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
