[link to original on tumblr]
---&---
I use the original tracks as templates when I record my own versions (I just play on top of them), and the talking at the beginning made it hard to sync this perfectly, so I don't have the tempo right at the beginning. I don't have the strumming rhythm right either (it's not even consistent between the two guitar tracks I recorded), but I usually don't pay much attention to that. This isn't the whole song, but I have at least one instance of each part (the song is just verses and bridges).
After I recorded this, I realized that every "home" in the lyrics is sung on top of a G major chord. The song is in G major, so the G major chord is the musical "home" to which the song returns too, just like in the lyrics. Only one of the "home"s is sung to a G note though: the one in the line "On our way back home." The others are sung to B notes.
The bridge is in a different key (I'm not sure if it's technically Bb major or G minor, but those two keys have all of the same notes), which - to some degree - helps portray the distance of the nostalgia mentioned in the lyric ("memories / Longer than the road that stretches out ahead").
