Oh, oh, I love it! DH and I watch it every year, mainly because we're lazy and CBA to go out, and more generally - we're not hugely into NYE anyway.
DH got me into Jools Holland because he was learning to play rhythm and blues piano just like JH does. Watching the acts - remembering years past like when Amy Winehouse was on it, and Lily Allen going on after a sensational set from AW. At that time (2006/2007 I think?) Lily was being a massive bitch to most of her peers and she took the piss out of Amy's coltish, leg-sticky-outy dance thing she did. DH and I were shouting insults at Lily through the TV, and Back to Black was such a profound, seminal album, and I dunno...it's memories :)
Last year Adele performed Someone Like You and it was a hundred times better than the studio recorded version she released a little later on the radio - for someone who only really listens to random songs, and never the full album and has very little interest in live music, I suddenly turn into a right old appreciator-of-music for one night only.
Much, much love for JH on New Year's Eve. I love how over-excited he gets, and it's all just such good memories, where everything is mixed in together. Watching Jools every year, so many NYE's past, listening to DH learning to play rhythm and blues, the various artists - I guess it's become a tradition of ours.
