You can usually open the YouTube app on your phone, play a video, and if your TV is connected to the same network, click the little "casting" icon on the top right corner and it will suggest some devices on your network - which hopefully includes your TV - and it will play on that! I find it so much easier to navigate to content on the phone than trying to use the Fire stick remote or the TV's (although my Fire stick you can just talk into and it plays it - which still childishly amuses me!).
Sinclair was of coursewell known for producing the C5, but I thought it was a pretty terrible street car myself
National Theatre is an absolute National Treasure (not the NIc Cage one). They are going thru some tough times - despite being at the forefront of dramatic arts and stage craft - and may not make it out the other end of this c19 apocalypse (this is according to the Director of the NT). Either way, stage shows and how it works out will be changed as many venues will simply not be able to reopen or reschedule shows or the myriad logistics around things that were in progress but just cant now be done. The economic and craftmanships cost is huge. Suggest we support with donations - or lobby BoJo and his cronies to do the right thing.
