The unlikely documentary that paired the New Zealand Symphony Orchestra with famed satirist Jeremy Wells makes it to the small screen this Sunday.

The Grand Tour, was filmed in late 2010 as the NZSO embarked on a massive European tour that coincided with the 64th anniversary of the NZSO's first rehearsals.

At the time NZSO Chief Executive Peter Walls was positive about the choice of host.

"We knew he was a great fan of classical music, and comes to our concerts, it just seemed like an excellent fit."

But promotional material for the documentary suggests he may have something to worry about.

"I'm not sure anyone will talk to me after the programme goes to air which is sad because I have a lot of respect for all the members of the NZSO," Jeremy Wells says.

"I was surprised at the amount of sex that occurred on tour, it's basically just a root-fest with instruments and buses."

*The Grand Tour screens this Sunday July 31 at 8:45pm on Prime.
