which Mozart's concerto did she play?

I remember when I watched Eurovision Young Musicans in 1996 I loved how the girl, who won 3rd prize, played Mozart. I found out her name - Hanna Heinmaa. However I could not find any information what she was playing. I know it is ridiculous question to ask but maybe somebody remembers this performance and knows which Mozart concerto she played??
