The musical was Camelot and I've found out that I got the part I was hoping for. I'm a knight of the round table. Huzzah! Just call me Sir Lionel.
If I'd been the auditioning panel, I would have refused me the part. I gave a shocking performance! The singing was particularly poor. It all seemed to last about 6 nanoseconds too. Still, I'll work hard at rehearsal to make my stage performance better than that. There were 4 parts on offer and 4 of us auditioning... so the competition was not particularly fierce. However, I'm still happy with the result, even though the route there was a bit sub-optimal.
I have a plan now.
