As Tonya is leaving the meeting with General Yevgraf Zhivago (Alec Guinness) he shouts, "Tonya! Can you play the balalaika?" and her boyfriend shouts back, "Can she play? She's an artist!" I always thought the boyfriend was a dam engineer (played by Mark Eden) but the IMDb Quotes says it's David (played by Gerhard Jersch). Is this right?
