Sing a line for a song !

[Vaquero Verbal]

Hi !

I´m working at a song and I have no idea how to sing (melody...etc) :-(
So here is a 12sec loop of the verse.

My question is :
Would anybody like to sing a few lines over this loop ??
I need some input, cause I´m no singer at all and not a good lyric writer too.

So maybe someone has an idea how to sing over this part and wants to try ???

Thanks
Dirk
