This week's theme: Disco. Yeah, sure, why not? ;)
And what better song to start with than the classic I Will Survive, released in 1978 by Gloria Gaynor on her album, Love Tracks. The song, about a woman who realizes she doesn't need her ex-boyfriend back in her life, was immensely popular back in the day and continues to be popular through numerous covers, parodies, and pop culture references (not to mention karaoke). Interestingly enough, George Carlin ranked this song #9 in his list of the "ten most embarrassing songs of all time." (Then again, lots of people hated disco. Who cares?)
Personally, I've also liked Victor Navone's Alien Song parody. In case you didn't know, the alien's name is Blit Wizbok, and he recently celebrated his 10th birthday.
