Hmmm...
London Critical Masses tend to start out that way, until the riders get separated. Quite a cacophony!
At other times I reckon the bells will be drowned out in the roar of traffic. And I don't have a bell - even if I were able to be in the capital on that day.
But I'm all for cyclists greeting each other - wherever they may be - with a friendly 'hello' or a nod.
Sorry: couldn't quite work out whether this was meant to be taken seriously!
