Never saw one of those shows. Did see a Vietnamese rock band in a hotel bar off Tu Duo Street in Saigon in 1968,
It was an interesting take on US culture as they sang “Mut Tang Sally! You bettah slow you Mut Tang down!”
Seen him in DEC 1970 at Camp Eagle, they brought in some dancers, Ursula Andress, Lola Falana and a very young Johnny Bench. The last song sang before they left was Silent Night. That was my first Christmas away from home (First time for many of us), had to wipe the tears from my eyes.
I loved their rendition of the James Brown song.....”I peel good”
