As Musical Director for Strictly Come Dancing, Dave Arch's music is always heard but he is rarely seen. Every week, the musician, composer and conductor, orchestrates his team and learns up to 14 songs every week.
There was the added pressure during week five for the special show celebrating the BBC's 100th birthday, with the celebrities and their professional partners taking to the dance floor to perform to well-known theme tunes from down the years.
The BBC show would be nothing without its in-house orchestra providing the incredible music for all the performances, which takes place in the iconic ballroom.
