Many of the sketches on Whose Line Is It Anyway? include music, and there have been a number of musicians during the show's run. Colin Sell provided the music for the original BBC Radio series, and Richard Vranch took over the job when the show was brought to television in the United Kingdom. Hall made her first appearance on the show when it moved to the United States for its final series, and she appeared on six of the UK series' episodes.[2]
Hall continued as the sole musician in the first season of the American version of the show. From the second season onward, Hall was often joined by multi-instrumentalist Linda Taylor, and other musicians were added occasionally.[2] Additional performers included Anna Wanselius, Cece Worrall-Ruben, Anne King, and Candy Girard. Hall has performed throughout the twenty seasons of the American series.[2]
Hall has recorded a number of children's records as well as Christian rock worship music. Her band is called The Sweet Potatoes.[4]
Hall performs at churches and conferences in the United States. She has led the music at Craig Springs Christian Camp's "Gap Camp". Designed for 18- to 24-year-olds, the camp is sponsored by the Christian Church (Disciples of Christ) and is held each spring in Virginia.
