The show was "Get Smart" staring Don Adams, he was Agent #86. His girlfriend was Agent #99.
The 80's Rock Group Toto who sang songs like Africa, Rosanna and Hold The Line. (BTW the group was named after Toto the dog from The Wizard of Oz.) Anyways, Toto also did a hit song called "99" in tribute to the Agent #99 in Get Smart. Hence the lyrics to Toto's "99".
The Belinda Carlisle song "Circle in the Sand" in the hint was because it was in the planter with all of the little white coral rocks (or what ever kind of rocks they are) which represented sand. Of course to get the cache out, you would have to start swirling your hand around in there to find it...Hence circle in the sand...
