The comedian, musician and Strictly Come Dancing champion is making a bid to represent the UK in Eurovision 2022, and confessed he is a 'Eurovision nerd' who has studied the secret to winning.
Bailey, 56, told ITV’s Lorraine: "There's lots of things we have to address, the key for example. I'm a bit of a Eurovision nerd - we've been doing these upbeat things in the Major Key.
"The last 10 winners were all in the Minor Key. We've got to be moody - don't mention heart, don't mention walking."
The UK has come last in the Eurovision Song Contest for the last two years, with the most recent entry, Embers bv James Newman, receiving zero points.
Bailey - who has previously written his own version of Happy Birthday in the Minor Key as part of a stand-up comedy routine - admits he does "hope" he might be given a chance to represent the UK in the song contest next year.
He said: "I just think we can d better. Surely we can do better than this."
Bailey previously revealed the BBC had rejected an entry he wrote Eurovision for being too "silly".
He said: "A few years ago I sent in an entry to Eurovision and it was a spoof eco anthem in the style of Dad's Army, the BBC said, 'It's too silly, we can't have that.'
“And I just thought, this taking it seriously, that's not going well either is it?"
The UK last won Eurovision in 1997 with Katrina and the Waves' Love Shine A Light.
Since then the UK has been placed last five times, and received 'Nil Point' twice - in 2021 and also in 2003 for Jemini's Cry Baby.
