The train stopped briefly at Queen Street, then rumbled slowly north. It could have gone faster, but Wales has a 75 dB sound limit in operation eight days either side of the Winter.

‘Have you been overwintering long?’ I asked, by way of conversation.

‘I’ve not seen a Summer for almost three decades,’ she said with a smile. ‘I remember my first venue: Hartlepool, Winter of ’76, the Don Hector Playhouse. We were performing King Lear as the support act to the Chuckle Brothers during their one and only Winter tour. Their gig was packed – almost three hundred people. Never seen that happen before except with the Bonzo Dog Band or Val Doonican, but then they made the Winter season a kind of trademark, like Mott the Hoople and Richard Stilgoe in the old days and Paul Daniels and Take That today.’

Few Summer acts chose to brave the cold – the Winter could be a hard taskmaster. The 1974 Showaddywaddy Welsh tour was a good case in point: the band were first trapped by Hunger-crazed nightwalkers in their Aberystwyth hotel, then lost half their number to an ice storm. Over the next two months their manager was kidnapped and ransomed by ‘Lucky’ Ned Farnesworth, three roadies lost their feet to frostbite, and their bassist was allegedly taken by Wintervolk. Aside from that, the surviving members thought it was one of their most successful tours ever.

‘Never realised how strongly the silence could drag upon one’s psyche,’ said my companion, breaking into my thoughts, ‘and how the solitude can become physically painful. I once went seven weeks without seeing a single soul, stranded in the Ledbury Playhouse during a protracted coldsnap in ’78. Colder than the Gronk’s tit and for four weeks a blizzard. Even the Villains hunkered down, and nightwalkers froze on their feet. Come the melt the rigor kept them upright – they didn’t start falling until they’d thawed down to their shins. For those not with the calling, the absence of humanity can be debilitating.’ She paused for a moment before continuing. ‘But y’know, in some strange way, I love it. Good for achieving a sense of  . . . clarity.’

Long-time Winterers were well known for expressing their views in this manner – a dark love of the bleakness, and how conducive the solitude was to deep philosophical thought. More often than not, those that extolled the Winter virtues so fulsomely did so right up until the moment they left an overly apologetic note, stripped themselves naked and walked outside into the sub-zero. It was called ‘The Cold Way Out’.

‘Lobster,’ said Mrs Tiffen without relevance to anything, still playing the bouzouki. ‘Help Yourself’, again, for perhaps the two hundredth time.
