Hi Dora, thx very much for this special video! It is really an historical document! What age does David had here🤔. I'm not sure but i guess around 40?? Time is passing so fast. All those People must be in their seventies now i guess when they have the luck of still living.🤞And they made during their days of 'isolation' there the beautiful number 'on my way up'. I didn't knew the number or never heard it before but i like it❤
