right Simon.
The song is in the key of G (for tenor) so there is an F# in the key signature….here is the problem;
I made some of the F’s in the transcription natural but the program didn’t make some of them natural as I though they would be.
I should of checked this closer to be 100% sure but it slipped by me.

so I updated the sheet music and reloaded it. Everyone should download this again.
I will email everyone with a more detailed explanation.
thanks for the heads up Simon!
