I was watching the Frontiers boot of Japan 1983 (Classicrocklady ROCKS!! THANK YOU SO MUCH!!

...which was only 2 years before.
All of a sudden, it seemed really ODD to see the Frontier-era-lower-register-Steve cranking up to a higher register to sing the Escape songs. It looked like he just completely changed everything about himself, including how he delivers a song...the slightly lower-register gut-emotion on "Open Arms", for example...it was no longer a "happy-here-I-am-with-OPEN ARMS!!" delivery....it was something altogether "darker"...
For those of you who have seen this....have you noticed this?
