Parodies pale on the topic of simultaneity of yule and yer own beeday.
The Radio Ate My TV has “We Wish You a Merry Christmas Happy Birthday Mashup” with The Muppets, Jackie Vernon’s Frosty the Snowman, John Denver, and more all stitched together to chilling effect.
And here’s a near miss, “We Wish You A Merry Christmas And A Happy Birthday (For Kelly And Paul)” by Kendra Masonchuck. Yeah it’s for twins, tweaking ‘Wish You’ only slightly. It’s Steamroller symphonic big, though, so that’s fun.
