When Sir Tom Jones struck gold in 1965 with his first number one, It's Not Unusual, his father was still working down the coal mines of the Rhondda Valley.
Known as "the miner's son from Pontypridd", Jones's life had moved far from the working men's clubs where he first learned to perform.
By his mid-20s, Jones had signed a three-record deal with Decca Studios, sharing a label with The Rolling Stones and cutting his first string of hits.
But the pop star said he never lost sight of home. Appearing in the BBC series, In My Own Words, he revealed the anguish he felt knowing his father was still down the pit while his own life was being transformed by fame.
The episode is filmed at the first home he bought with his late wife, Linda, in 1966 following his first wave of success.
