The Undertones - Listening In lyrics

I was sitting on my own No-one there till I picked up the phone And then I heard your voice I was listening in You were talking in the hall I wasn't there but I heard it all Nothing I could do Just listening in On the carpet you're so small He had you covered wall to wall Nothing I could do Just listening in Now you're gone and your line's dead Nothing I can do instead No more, no more No more listening in
