Please help me find a song, here is what I know about it:

I was watching vh1 in Acapulco and this video was on during the top 40 (I think):

It was a group with 2 females and 2 males.

the girls were very pretty

everyone takes a turn singing in the song, and the four of them are sitting in a row, like an acoustic session almost.

the video looks like it was made in the 70's

the chorus goes: Wooh wooh and then a line in mexican

that is all I know

Please help me

It was aired either 4/22/06 or 4/23/06

thank you
