Another great Toto song.
The verses are pretty clear, "Not quite a year" starts the pre-chorus, and "Meet you all the way" is the chorus. After the break, we come back to a pre-chorus. The extra jam at the end is just an extended coda.
This song came on the radio one time, and my wife pointed out that the guy who wrote it was obsessed with Rosanna Arquette. My daughter said "Really?" and I said "Yes, he loves her so much, he's not just gonna meet her halfway, he's gonna meet her all the way." Which, if you think about it, doesn't make any sense.
