For the residents of Talgarth in mid-Wales, it's the green, green grass of home, but they were still surprised to see Tom Jones in the area.
The Welsh star's likeness was spotted by fans in a photo of the Black Mountains in southern Powys.
Andrew Sheehy, from Blaina, who took the picture, said: 'I went for a walk in the Black Mountains near Talgarth and came across this amazing shadow face of a man.

'I posted this on the Facebook Brecon Beacons walking page and it's gone viral... with everyone saying it's Tom Jones singing.'
Jones's recording of Green, Green Grass of Home was No 1 in the UK for seven weeks in 1966 and has sold more than 1.25 million copies.
The 79-year-old's string of hits over the past 50 years also includes It's Not Unusual, Delilah and Kiss.
