I'll Be Home For Christmas- A John Watson Christmas
Once In Royal David's City
O Come, O Come Emmanuel / God Rest Ye Merry Gentleman
John was raised nominally C of E, just like most other kids his age. Church was likely on Christmas and Easter, and every so often his mother would feel guilty and drag Harry and him in ill-fitting dress clothes to the old stone church at the heart of town. But then, after a while, she'd give up again, and they could sleep in. He'd figured Christmas Eve service was alright; they didn't have to wake up early for it, and the music was pretty. But that was really about it.

I Saw Three Ships
Harry was the one who'd gone mad for Christmas- before she'd become an early-middle-aged alcoholic divorcee, she'd been a rather good singer, and at some point in her pre-teens had gone round the twist for medieval Christmas music. Her tastes had branched out a bit as she aged, but every year she'd send him yet another Christmas album, which he would dutifully listen to, and then put away for another year.
Spered Hollvedel
A Midwinter Waltz
The Seven Rejoices of Mary
Some of them had been interesting, some god-awful, but he'd ripped them all into his mp3 player before he left the country, and had nearly single-handedly supplied his unit with tunes his first December in Afghanistan. Harry, of course, had sent him three new albums that year.

Little Drummer Boy / Silent Night / Auld Lang Syne
Mistggerlou Joaius
The next year had found him sharing a base with a bunch of Americans, who all seem to be universally holiday-obsessed. He'd offered up his collection, and they'd shared theirs, and he'd ended up with whole playlists to give to Harry when he got back- Jimi Hendrix, Odetta, and at least one carol in a First Nation tongue. He couldn't wait to show her.
The Ditchling Carol
Oikan Ayns Bethlehem
Jesus Ahatonnia (The Huron Carol)
Noel Nouvelet
The side benefit he hadn't know of at the time, of course, is that when Sherlock discovered a whole new source of music he'd never even heard of, he was delighted for at least 15 minutes. He's since learned it all, naturally, and skips through it on his violin while he thinks. At some point John noticed there was one more track at the bottom of his list- a French carol.
He's never asked how it got there.
