The singer and producer - who worked on 'Teardrop' alongside the likes of X Factor judge Tulisa Contostavlos, Ed Sheeran and Ms Dynamite - described the experience as "very healthy".
Labrinth told Digital Spy: "I worked with Tulisa on the Children In Need single, and I remember her saying that she was very nervous about how she would be received on the show.
"It was a nice surprise to be asked by Gary [Barlow] to produce the song - everyone left their egos at the door and the whole thing felt very healthy."
Asked if he was nervous about producing the track - a reworking of Massive Attack's 1998 original - he admitted: "I love that record - it sells itself! I didn't want to fiddle with it too much because you can't spoil a record like that. Eventually we found a way around it - the finished version sounds great."
'Teardrop' is released on November 13. Labrinth releases his new single 'Earthquake' on October 23.
