On videoclip is funeral and it's snowing .This is slow little christmas song. Anybody know?

Hi, I also want to find the song but I don't remember anything except some moments of YouTube video

So the video was kind of retro (retro car's clothes like in 60-70's). The video starts in the kitchen with pinup like blond girl and then she goes otside singing. If I correctrly remember, then she is outside there is a lot of singing people and retro car in the back (something like russian volga). The video colors were very juicy, sunny. Video is quite new, maybe 2011 year. Something not older than 2008 Can somebody try to help me?
