Hi mate.

The concerts in Scotland never usually sell out or if they do, it's much closer to the date and Murrayfield is quick a bit bigger than Hampden capacity wise.

Take That are doing 3 shows in Glasgow at the same time (hence why Jovi are in Murrayfield) so tickets won't sell for Jovi as quickly either imo.

Murrayfield is actually a pretty good stadium for gigs. I'd take it over Hampden or Ibrox any day. You can spend the day in Edinburgh and then walk to it in 15-20 minutes. There's some nice pubs and restaurants nearby etc...

Fans will definitely be singing along and the only real difference you might notice is there'll probably be a lot more drinking going on than English shows.
