I thought maybe the intro could be different featuring everyone wearing a covering mask, and the lyrics could be altered like the Tegridy Farm one:
"Goin' down to South Park, gonna have my self time,
Covered Faces everywhere, annoyed folks without temptation,
Goin' down to South Park, gonna leave my woes behind,
Wearing a mask all the time, people spouting "Screw you, Covid!",
Heading up to South Park, gonna see if I can't unwind,
I want to see lovely bitches, but I can't because of that plague,
So come on down to South Park, n' meet some friends of mine"
