Like this band a lot. Not sure how "popular" they were. John Lennon played "A Whiter Shade of Pale" all day in his Roller.
You know after a bit of reflection... The stronger pot often just knocks you out. So if you consider knock out pot good...I had some Thai weed many years ago that could put down the most hardened smoker in three hits. As in your on your back waiting for the world to stop spinning... Just not my thing, I want to be high not out. But some Thai can really take you home.":O}
The Thai boo I smoked in Southeast Asia was a lot different from what's called "Thai weed" here in the US. The sticks were a robust 12 inches long of fat buds tied to the stick with a sliver of natural fiber. We had two varieties, Temple Weed and Buddha Weed. They were both amazingly strong but one of them was dipped in liquid opium. Hilariously the aerial MI company across the runway sent me a lot of their radios to be repaired "Urgently." These were avionic shortwave radios that were large and heavy. Sliding the radio out of its long case left a lot of room for most excellent pot. Somehow the planes that they flew home to Danang after a visit to Thailand sported "INOP" shortwave radios. No sheeit Sherlock! The higher ups in that Military Intelligence Aviation company became po'd with me because "my" radios failed so very often. I learned to chuckle when that outfit's flying short wave radios returned to me after being called inoperable. They failed so very, very often. The front of the case seemed normal, the usual part being left in place. But The Collins (censored model number) short wave unit had difficulty operating when it was nowhere near the plane. Actually that particular radio was one of the very best quality that the army had. Fine machines that were the envy of every Ham Operator on the planet. Memories, memories.
