Alligator (Tegan and Sara song)

"Alligator" is the second single taken from Canadian rock duo Tegan and Sara's sixth studio album Sainthood (2009). It was originally released in the United Kingdom in October 2009, a day before the release of the album, as a digital download. In March 2010, the single was released 17 track remix album in the United Kingdom, United States and Canada as a digital download and 12" vinyl. The single charted at number 32 in the Billboard Hot Dance Club Songs.

Sara has stated that the song "was the first song I wrote for Tegan and Sara that didn't involve guitar whatsoever. There were lots of songs I'd written where I took guitars out or fooled with the instrumentation later on, but Alligator was the first song that I sat down and wrote without even thinking of the guitar. I picked a piano riff that I thought was cool, looped it, and just started building from there."
