Is he saying, driver blow your horn, driver blow your horn, driver won't you blow your horn, beep beep! Cuz to me it sounds like 'dying to blow your horn' but that just doesn't make sense! This has been annoying me now for a few weeks.
I also wish I knew what he is saying. Sounds like "Dynamo to blow, dynamo to blow, dynamo to blow your horn beep beep." but that makes no sense either. What are they saying to our kids? Although I'm not that worried as its Justin Fletcher's voice.
