---&---
A couple days ago, I read this Rod Argent interview (which is pretty decent compared to most; part of it is Argent's standard answers to common questions, but it does branch out a bit). He talks about a couple of the earlier Argent songs, including "Rejoice" from Ring of Hands.
This morning I was playing various Zombies things on piano, and just before I quit, I played the opening (which is also the closing) phrase from "Changes." Because I recently read that interview (in which Argent briefly mentions the structure of "Rejoice"), I realized that both "Changes" and "Rejoice" have an introductory keyboard part that's repeated at the end as a conclusion.
