Has anyone else besides me noticed that out of all the characters, Simon's voice is never really consistent? All you have to do is watch random episodes of the 80s cartoon for evidence: he starts out sounding like an only slightly lower version of Alvin, midway through the series (as well as THE CHIPMUNK ADVENTURE) there's less squeakiness to his voice and almost sounds like a high-pitched kid, then in later episodes his voice is much deeper and more deadpan (and kind of nasally too). The last I heard Ross and Janice doing the voices, which was the "Ho Ho Ho" song, Simon now sounds just like Alvin, but the only way you can tell them apart is Simon's speech pattern is obviously more articulate than Alvin's.
