They were in a band called S.K.W.A.D. but they split the band up to form Straight Lines, so that sticker is most likely from the S.K.W.A.D. period as it's been there for a long time.

Todd and Dane are very talented musicians, but they've gone down a pretty different path from their old man. This is what Straight Lines came from, and you can see the similarities.
