A third version in Mandarin I know of is by Sakura Teng and the Quests.
I lost the bidding for the record (again) but I cleverly robbed the picture sleeve, so here it is.
If anyone wants to share the song you'd make me a happy man.

Meanwhile check these posts for the Betty Chung and Lara versions with picturesleeves and music or other Chinese Eurovision covers by Shirley Kwan and Annabelle Lui
And a recommended blog for Asian pop currently featuring another Sakura Teng EP is Mod-ified Music. Worth checking out now! UPDATE Also check this post at Mod-Ified, it has one of the most absolutely poptastic coverversions of Love Is Blue (Luxembourg 1967) from Singapore.
