This is one of bossa nova classics; Aguas de Marco. This is the original in Portuguese, sung by Elis Regina and the songwriter, the godfather of bossa nova; Antonio Carlos (Tom) Jobim.
Here is the English version, called Waters of March by Oleta Adams and Al Jarreau.
The last one is in French, called Les eaux de Mars by Stacey Kent.
I love all three of them. Which version do you like?
