Pixies frontman Frank Black has found a new labour of love - changing his baby son's nappy.

The cult rocker insists nothing thrills him more than making his child comfortably clean.

And he believes the time they spend together is building a psychic bond between them.

He explains, "He loves it because he's got s**t smeared all over him, and it's bothering him.

"I lay him down in an area where I change him, and he's psyched. He's laughing and going, 'Wah.' He can't believe his good fortune.

"We're looking at each other, and it's psychic, and we're talking and laughing, and just having a really good time."
