I was there on all three nights and I reckon it's most likely 'I'll be lightning' wasn't included because on Night Three (from whence most of the performance footage is gleaned) Neil was singing along with Liam and made a mistake in the song. He alludes to it in a couple of comments that made it to the final cut we are all now currently enjoying... the first mention is around the time of 'Throw Your Arms'... At the time I recall he was really down on himself for stuffing it up and apologised profusely to Liam. Jason was supplied a beautiful mix of all three nights that Neil had put together with Jordan Stone based on the best performances. That then had to be paired with the best footage available from all three nights and the third night seemed to have the most complete footage. That in itself is a massive reverse engineering brief and I reckon Jason did an amazing job. Granted, it ain't Speilberg, but it was done gratis, with a massive injection of goodwill and human kindness at the heart of it and it's way and above what my heart could ever have really hoped for. I couldn't be more thrilled and appreciative. On ya Jason! You've certainly rocked my world!
