Tamsin Kelsey (Lulu) later featured in two episodes of Stargate SG-1 alongside Richard Dean Anderson again.
The character Lulu asks how old MacGyver is and he says he is 39 years old. That means Angus MacGyver was born in 1951, or that he was born in 1950 but hadn't had his birthday yet that year.
The beautiful piece that Lulu plays on the Stradivarius named Amadeus in front of the people is Movement Two of Mozart's Eine Kleine Nachtmusik, also known as Romanze.
