Yes, Thierry was invited to perform in the historical museum of Lippstadt. I could choose between several of their rooms and after seeing that the public were mostly elderly people, I decided for the Baroque/Rokkoko room and an adapted program.
Before, when Wolfgang asked me if I would perform in public, I wasn't at all sure if I should. First, until now I played only for myself, thinking that I wasn't yet good enough for a public performance (I still do think that!) Second, the day before this performance Lydia had harshly criticized my vibrato and my phrasing (among other but less important details). So I couldn't already not fall back in my old style, but hadn't yet adopted the correct one (am still working hard on this).
Finally I didn't want to deceive Wolfgang and the really friendly museums' director Dr. Poetter and I went there.
Seen the Public and the environment, I started with Rachmaninovs Vocalize (with piano accompaniment from my MP3-Player), told then people a bit about the Theremins' history and playing technique and answered to their questions. One man wished that I should play something more popular, so I played the Wiegenlied from Brahms (without any accompaniment), telling that I play it sometimes in the evening for my four daughters. Then, as a tribute to the marvelous room I played the Air in G from Bach (with MP3-piano), invited people to come in the evening to the festive final Concert with Lydia, Barbara, Carolina and Wilco and finished with the Swan.
OK, this more or less spontaneous action taught me that on one side the average public has perhaps not so high expectations as I have for myself. So you will still have to wait some more years until I appear perhaps on YT... On the other side, I learned for myself that I might do such things in case it would be really needed
