It really doesn't look any different than any Dennis Kenyon air show routine. Less dangerous even. Indeed, Dennis's fascination with dragging and spinning his skids around on the ground always scared me to death. As an R44 pilot I doubt he was anywhere near busting MP or sideways speed limits. Inside the HV avoid area, though, certainly.
Disclaimer: yes, yes, air shows are best performed over less forbidding terrain and not over people. And no, I don't fly like that myself, although I do enjoy a good pirouette at IGE heights from time to time.
