International producer David Foster was the musical arranger and host for a very special night.

He is famous for guiding the careers of everyone from Celine Dion and Josh Groban to Michael Bublé, Barbra Streisand, Whitney Houston, Chicago and, of course, Andrea Bocelli.

Foster told the audience, which included Sir Michael Caine, how the very special duet came about.

He said: “When we were in the studio making this album, we wanted to do this next song and we wanted someone to demo it.

“Andrea said, ‘Well, my beautiful love Veronica she sings of course.'”
