Jamie will be compering the annual Christmas at the Movies concert this Sunday and, frankly, is thrilled that this year's theme is animals.
He and the BBC Scottish Symphony Orchestra, conducted by Stephen Bell, will have their hands full with a menagerie's worth of film animals, from Dumbo and the Lion King to Jaws, the Pink Panther ... and, yes, even Jurassic Park.
Mince pies and mulled wine will be on sale, swelling the festive atmosphere.
"They're billing me as Dr Doolittle for this show," laughs Jamie. "But my mother would just call me 'Dr Do-Damn All'!
"There's a great repertoire of songs at this concert. I'll be singing Elton John's Circle of Life, from The Lion King – I'm looking out my best wig for my Elton impersonation.
"We're also doing the same arrangement that was done for Frank Sinatra for A Nightingale Sang in Berkeley Square ...it will be such a highlight for me.
"We're doing the music from Dances With Wolves, the title theme to Born Free, which Matt Monro first sang all these years ago, and songs from The Jungle Book, Shrek, Harry Potter and Wallace and Gromit, too.
"One of my favourite screen actors was Danny Kaye, and I'm delighted I'll be getting the chance to perform Hans Christian Andersen, who Kaye played in a Hollywood musical back in 1952. That is going to be such a thrill for me.
"The show is aimed at all ages. We've got a good number of cartoon songs: the Bare Necessities from Jungle Book, and Dumbo, but for the adults there are things like Born Free, the theme from Jaws, ET-we've really spread the spectrum.
"There maybe weren't too many child-orientated pieces last year, when the theme was superheroes, but we've really gone to town this time."
Jamie, 45, has become an established voice on Radio 3, and appears regularly on television thanks to his hosting the BBC's Last Night of the Proms celebrations in Scotland.
He will host BBC Radio Scotland's Christmas Classics at 3pm on Christmas Day.
All of this is in addition to being one of the country's best-known classical singers, equally at home in the recording studio as he is on the concert platform of the world's leading opera houses.
He has also been touring a one-man show on the life and legacy of the great Scottish performer, Kenneth McKellar. "We got great feedback from it and we're going to be revising it next year, as well as looking to record material from the show."
His distinguished singing career began when he won scholarships to both the RSAMD in Glasgow, and London's Guildhall School of Music, and he made his debut with the English National Opera. He has since sung with some of the world's top baroque, chamber and symphony orchestras.
"It's been a good year for me personally," says Dennistoun-born Jamie, who is one-third of the popular Caledon singing trio. "I've been broadcasting classical music on Radio Scotland for 10 years, and that has been fantastic fun. From that I've had the chance to work with the BBC SSO.
"I can't think of anyone else who has the chance to work in this way and perform, on a regular basis, the repertoire that I do.
"I know how lucky I am, and I revel in the fact that I can both present shows, and sing with orchestras such as the BBC's."
Jamie's schedule in 2012 continues the hectic pace set by previous years.
"I'm going to Seoul, South Korea, in January. I am back for a week then off to Mexico for a few concerts there, and after that I'll be off to Australia to do a Scottish concert with the Adelaide Symphony Orchestra. That was something that was supposed to happen in 2013 but it has been brought forward."
More immediately, there's the small matter of this Sunday afternoon's gig at City Halls. Jamie will be keeping his eyes open for any child who has come dressed as his or her favourite animal. And there may just be a small prize for the best one.
