It's interesting that it wasn't that band they mentioned. Rather, the Rolling Stone mobile recording truck. The Stones commissioned it, but it became so popular that it became a business used by many bands in the early 70s. Deep Purple was waiting their turn to use it when a fire started during the Zappa concert. It was caused by a fan with fireworks. Thus the storyline of Smoke. Btw DP used the truck to record Machine Head, Burn & Stormbringer

They are quality & very flexible. Mine are the most capable coolers Ive ever used. I work outside & they take care of me all day in the hot Florida sun. Good luck!

Try Goojodoq bluetooth sleep headphones, $29 Amazon. I went thru the process looking for sleep comfortable headphones & these are the best i used. I can wear them all night without that headache feeling. The ear pieces are thin enough to lay on your side without being noticeable. That is the thing that makes them stand out. Sound quality is ok, after all my goal is to fall asleep & stay asleep rather than appreciate music for hours. These are very light & look fragile but i have used them most nights since i got them August of 2021 & they have held up just fine. For the price its worth a try

Check out Polar Bear coolers. I have 2 Ive used for 10 years now & they perforn really well out in the hot azz sun all day. Waaaay cheaper than Yeti.

I bought a Jetta GT new in 97' . It made it to 370k miles til my daughter drove the wheels off it. My next door neighbor had an 88' Jetta TDI he bought new. Constantly drove it, courier by day/pizza by night. It had over 500k miles on it when he traded it in for a Jetta Sportwagon
