It got me thinking:
Has that era of Journey - with Steve P. at the helm - gone the way of "impersonators", such as those I've listed above??
Seriously - does that give respect to or hinder the whole genre of Journey's music...and Steve Perry, as a Singer?
I'd love to read your thoughts on this....and Lora & Cyndy...if you're out there:
What do YOU GUYS think of this?
