AH64 Apache - can they roll?

[Zippee]

I was wandering if anyone can help settle a query;
At an airshow a few years ago I swear I recall seeing an Apache doing a roll or loop during its display but my friend says the only helicopter capable of this is a Lynx. Whos right? Is an Apache capable of performing this kind of manouver?

Thanks chaps! Though I'm a little confuzzed as that youtube clip clearly shows an Apache doing a loop??
