The 15-second clip gives little away, showing an artistically-shot promo teaser which is set to the soundtrack of a sizeable string and brass band.

The full version will be revealed to the world on Friday 25 September. 

Sam first confirmed he had been chosen to provide the acclaimed music track for the latest 007 installment earlier in the month after initially denying all speculation.

Finally coming clean, he announced the news again on his Twitter page with help from a photo of his hand clad with a Spectre-logo ring.

Calling it one of the highlights of his career, he added: 'I am so excited to be a part of this iconic British legacy and join an incredible line up of some of my biggest musical inspirations.'

Opening up about the 007 experience to Nick Grimshaw on BBC Radio 1's Breakfast Show the following day, the Omen hit-maker said it had been  a 'top secret mission' of his own, admitting it was the quickest he'd even penned a song.

He began: 'I'm so relieved to actually talk about this, this has been a top secret mission of my own.

'I got called into the office with (producer) Barbara Broccoli and (director) Sam Mendes and they gave me the script, I read the script ... they said, "Have a go at the song".

'It's the quickest I've ever written a song - it took 20 minutes - and they loved it. I love the song so much.'  

A four-time Grammy Award winner with five No1s under his belt, Sam becomes the first British male solo singer of a James Bond theme song since 1965.

There was fervent speculation that he was involved in the track earlier in the year but it was previously shot down by the singer when he told Capital FM's Dave Berry and Lisa Snowdon in July that he 'had no idea what is going on'.

He explained: 'People seem to think I'm doing it but I have no idea what's going on. I'm being deadly serious. I think I would know by now.'

He added that believed singer Ellie Goulding was going to record it, though he revealed to BBC Radio 2's Chris Evans that producers only told him the news six weeks ago, to avoid a leak.
