Perhaps this has been brought up before, perhaps it is something well known that I don't know about.
In Blast Off! at the very end where it quiets down and he sings "oh no, who is it here that I see" is it just me or does the background music sound like El Scorcho. I am not as hardcore as the rest of you but I don't think El Scorcho was a SFTBH song, otherwise it could a cool reoccurring riff. But maybe that riff lead to the El Scorcho riff.
I don't know if it is the same, same notes but in a different key, or not similar at all, but to me it sounds similar to me.
