Hi I'm new to this forum.
I am looking for a Stones song.
It goes G D C G F C
And the last line of the song goes something like this;
"If you don't beleave what I'm saying at three oclock in the morning I'm singing my song to you."
It might be on the Let it Bleed album but I'm not sure.
It is a slow bluesy soulfull tune but I don't know the name of it.
Help, Thanks ,Rx
