Can someone please help me fish for the Title, Lyrics and artist of a supposed Portuguese samba number that I can only hum two measures from? After exhaustive internet searches and research the only solution I can think of is to sing the small portion of this song over the phone to someone who thinks they might be able to help me identify it. I have heard the song various places so it isn't utterly obscure. PLEASE HELP! I need the song for a musical revue I'm writing.

Cheers,
