A woman gets completely covered in green slime, sprinkled, gunged with chocolate syrup and pied in the face during the Deli Girls' (Tommi Kelly and Danny Orlowski) performance streamed as part of the A2B2 Night of Fire event on 13th November 2020. Quite a mess for some music event.
In the video, Tommi Kelly is the guy playing a piano in the background; he gets pied at the very end (the penultimate picture below). The tattooed singer in a leopard panties is Danny Orlowski. The messy girls is credited as "Sally".
Although the video above is better, here is the full "A2B2 Night of Fire" event if someone for some reason wants to see it (the Deli Girls' part starts at 3:44:02): https://youtu.be/qjw3O5nq45g?t=13443
