What song is this?

[machineman9]

I found a song earlier and I am wondering what the first bit of the song is, right at the start, because it seems very familiar.

War Sweater

Between 0 and 25 seconds is just the song I am looking for. It sounds like it is just music overlayed an existing song.

Am I mad or is that a different, more famous, song?


Cheers.
