I've decided to explain this progression in a little more detail. So, here is the complete theory version:
1 / 1 chord
#1 / major 6 chord (secondary dominant)
2 / 2 chord
3 / 1 chord
4 / 4 chord
#4 / major 2 chord (secondary dominant)
5 / 5 chord
#5 / major 3 chord (secondary dominant)
6 / 6 chord
7 / 5 chord
1 / 1 chord
Thanks, Teach. This now makes it easy to translate into every key.
