Brett Every this is not my song

They tell me this is my song
But i've not heard it before
They say i wrote it, i think they're wrong
I would never hold this court
Well they tell me this is my tune
But i just don't recognize it
They say i wrote it, i think they're confusing me with the other guy
And I just don't know how this goes
And i can't decide, sing it low or high
And I don't know when or how it's meant to end
So she came back to her shopping trolley
Found a child in it, not hers
I came back from that solo to find someone else's verse
And I still don't know how this goes
And I can't decide, sing it low or high
And I don't know where or how it's meant to be
I still don't see how it's done by me
Cause this ain't my song, it's a sing along
But I've never heard, so I don't know the next ...
