Yamit Mamo wrote in her myspace blog that she recorded for the title track of Death at a Funeral.
In her own words:
Anyway, lets begin.. Today [December 7, 2006], I recorded at the legendary Air Studios for the very first time. That in itself, just an amazing experience.. However, thats not all, noooo!
I actually went in there to record the title track of a new British film, Death at a Funeral.. I just dont know what else to say but Wow really.. I had an incredible day, met a whole bunch of insanely talented people and to top it all off, I was directed by Frank Oz (the man of many voices including Yoda, Miss Piggy, Fuzzy Bear and Elmo).
