What is the name of the group that remixes popular songs to sound like Frank Sinatra?

[Nathan Bobathan]

A long time back, I heard (quite hilarious) remixes of rock and rap songs that were made to sound like the vocalist-heavy genre of music sang by artists like Frank Sinatra. After a long search on youtube, google, etc., I have had no luck in identifying this group. It would be great to be able to find them!

Thanks in advance.
