It is highly unlikely they will have any of the big names like Josh Groban, Sarah Brightman etc.
Too expensive for one thing.
For the concerts in England, the "special guests" will probably be local, somebody popular with British audiences.
In Glasgow, I would like to see them give this local gal a chance - Eilidh Grant, from a traditional musical family.
She sings a variety of folk songs, love songs, traditional Scottish songs in English or Scottish Gaelic.
Another young Scot who was very popular with the audience when he won "Britain's got Talent" last month,
is Jai McDowell from Ayrshire on the West coast of Scotland.
He has a great voice, and I could see him fitting in.
