If you want, you can play Part 1 in the gap between Part 2 and 3. I dont think thats how 
is on the record, but it fits alright.

Part 3 - Come in when Katie sings "Keep your head" for the 4th time.

Play Part 3 until the end of the song, but finish before the synth and guitar so they 
play the last 4 repetitions of the riff.
