Mr Tucker said his favourite songs to perform in the film were My Way and She’s The One as both were pivotal emotional scenes.
In the film, the latter is done as a duet with All Saint’s singer Nicole Appleton – her character’s singing voice was provided by West End performer Kayleigh McKnight from Sawbridgeworth in Hertfordshire.
She beamed: “Knowing that there’s people all over the world hearing my voice when they see this film blows my mind.
“There’s something kind of fun about it. I was sat in the cinema watching it, and no one knew it was me… I felt like a bit like the Masked Singer.
“I’ve been dreaming of a number one in the download chart, and now I’ve got one. Maybe not quite the way I was expecting. I was manifesting it clearly, but I just didn’t realise it would be in the Robbie Williams biopic.”
