Thanks!Yeah , I had heard about that before
They are not actual doctors, Ben Toury and Brendan Kavanagh are two awesome musicians who sometimes like to dress up (e.g. as construction workers, or, in this case, doctors) to deliver impressive performances in public spaces and on youtube.
Definitely worth following!
I actually saw one more video, where they are not "dressed up" (they were wearing jeans and jumpers), but(!) the younger dude took an adhesive tape, glued his 3rd and 4th fingers together (on both hands), so that he couldnt move them at all, and thus, he played a very difficult boogie-woogie piece. Of course, they impressed everyone. But i have to say, they both have an awesome technique (it would have taken me a year to learn any of those things,- no kiddin', lol).
I'm not a big fan either,- maybe because i know that i'll never be able to drive a car (not because of health issues, but because of those stories with the mad house, which is like an eternal stamp on my forehead). But my dad had a car - Zhiguli 5 (Lada). [I was telling you about it last summer]. And as soon as that car was making us (dad and me) feel like family (for many reasons),- i was fond of it, and that particular "Zhigulyonok" was very special for me, because it meant a lot to dad.
Anyway, since my childhood and younger years, i learned to respect cars, sane(!) drivers and car manufacturers. ...But i still believe that vehicles pollute the environment (though meat and dairy industries pollute it hundreds and hundreds times more).
