Unknown song - needing help - second try

I got a song from a friend of mine - it's an mp3 on a USB-Stick. The 
recording is in poor quality, so I don't understand all the lyrics. I like

that song very much, but I do not know the song, and I do not know the 
singer....
Maybe it's the wrong forum - but who knows nothing, knows nothing...I 
apologize.
You can listen to the sound here:

I hope some of you know that song, or at least the singer. I would be very

glad if you could help me.
