[5] One of Sand's fellow cast members in Story Theatre was actress Valerie Harper, who, in 1970, had been signed to play Rhoda Morgenstern on the CBS-TV situation comedy The Mary Tyler Moore Show.

During that show's first season, Sand was cast as Robert C. Brand, a tax auditor, who falls in love with Mary Richards (Moore) in the 11th episode "1040 or Fight".

MTM Enterprises produced Friends and Lovers, in which Sand portrayed Robert Dreyfuss, a double bass player in the Boston Symphony Orchestra who falls in love easily but has little success with women.

[6] Sand also appeared in such motion pictures as The Hot Rock with Zero Mostel, The Second Coming of Suzanne alongside Sondra Locke, and The Main Event starring Barbra Streisand and Ryan O'Neal.

In the fall of 1986, Sand, along with comedian Rosie O'Donnell, joined the cast of the NBC sitcom Gimme A Break starring Nell Carter, then approaching its sixth year on prime-time television.
