Hi GSS

<" I had to make up some words, no one noticed, in my opinion to some extent that is what performing is about,">

I couldn't agree more.

I had to do that sometimes but managed to keep up my performance.
On one occasion I actually forgot the tune of the song I had introduced. I just sang the words to a tune I made up as I went along.

All performers whether professional or not make mistakes. But the best ones make only a few and know how to cover them up.

Cheers
