Gene Pitney
From Tardis Wiki, the free Doctor Who reference
Gene Pitney was a famous human who, according to Owen Harper, "bugger[ed] up the Cardiff tourist trade".
While on tour in Cardiff, he was found dead in a hotel close to Blackfriar Way. Owen joked "I think something got a hold of his heart". (PROSE: Another Life)
Behind the scenes
Owen's joke "I think something got a hold of his heart" is a reference to Pitney's single "Something's Gotten Hold of My Heart".
