My parents took me and my cousin to see
Beauty and the Beast at the Edinburgh Playhouse when I was REALLY young. Must've been about four or five, and I have only very hazy memories of it. Even then, it's barely anything. I actually remember the fire alarm going off in the hotel way more than the musical itself

I'm pretty sure they got me a Lumiere plush, though, but it's long gone.
I saw
The Lion King in 2010 at the Lyceum when we visited London. The seats weren't very good (we were near the front of the Grand Circle) but I was happy to see it because I had wanted to for so long. I didn't think I'd ever get the chance to see it again, but then it ended up touring in Scotland in 2013 at the Edinburgh Playhouse. I saw it in October of that year and it's something I'll never forget. This time we had seats in the Stalls, a few rows from the stage, and it was mesmerising from start to finish. I'd do anything to be able to watch it for a third time.
