I can understand the apprehension, the expectations.
When they announced the Led Zeppelin Celebration Day concert I was apprehensive, it had been 27 years. But after that initial 10 seconds I was one of the 20 million who broke the system trying to buy tickets, and was only half joking when I told the firstborn she might be traded for tickets.
And they were magnificent, Jason stood in for his dad wonderfully, but that was almost 25 years ago. Now, men in thier late 70s and 80s, no way they could pull off a Led Zeppelin show. I would not want to see it, I saw Zep twice and Page and Plant once, let them live in my memories...
