I can remember several years ago with my old rock 'n' roll covers band at various Christmas time gigs we jazzed up 'Winter Wonderland' in a medley with 'Nivram'... i.e. Nivram/Winter Wonderland/Nivram, or something along those lines... it worked perfectly aswell! We couldn't keep a straight face or contain our laughter while we did it though!
The things you do for a laugh (and money!), eh??!!!!

I must add that that was a very, very rare example of us playing Christmas songs... we were a hardcore rock 'n' roll band man!
