It's a great show but you can't help but think the reason they brought it back is because of how well the live show went in the hydro last year. So much so they are doing another in a few months.
Cheapest ticket is £40 up to the likes of £200+ for hospitality.
13,000 people 3 shows a day at £70 a pop is £2.73 million per day. Mostly profit too.
On top of that they have merchandise sales. They had 2 shops selling unique stuff you could only buy at the show. Probably easily walk away £3 million plus per day.
I imagine they brought the show back to keep sales of live shows up.
