The husband and wife singing duo, Steve Lawrence and Eydie Gorme, guested in The Nanny in episode #2.16 -
"Canast Masta."

This episode appeared in the second season and aired on January 9, 1995.

Fran, her relatives and the Sheffields take a trip to Atlantic city so that Brighton can compete in a canasta tournament as part of the winning Flushing Queens team.

In a short, but cute cameo, Steve and Eydie get mistaken as look-alikes for themselves by Fran.
