Here's the lessons for the Rockschool Electric Guitar Debut, Oasis - Live Forever.
You can see the play-through of the piece here, along with the tab which shows you exactly which part of the music is being played.
This should really help if you are learning the piece and need to see how the written music fits with the song, or if you just need a refresher or it's great to use just to practise your playing.
If you need a bit more teaching, then you'll want the full lesson which is here.
This covers
all the chord diagrams,
where to put your fingers for each part,
how to count the music,
hints and tips,
a walk-through of every note,
and more
