I can't imagine flying a 747 for 10-12 hours (from the UK to Brazil), getting off, doing a 3 hour concert, then getting back on the plane and flying to your next gig. Even with a day or two off, that's an insanely hard schedule.
Props to him though, like you said, he claims the band saved a ton of money doing it that way.
From what I recall above a certain MTOW a type rating is required. So, certainly you need multi-engine category & class, the complex, high-performance, and pressurised-cabin endorsement, and a type rating, and then you could fly your 747, but only VFR :)
