Brett Page, Writing for Vaudeville
“ Extravaganza is anything out of rule. It deals comically with the impossible and the unreal, and serves its purpose best when it amazes most. Relying upon physical surprises, as well as extravagant stage-effects, the extravaganza act may be best explained, perhaps, by naming a famous example—"Eight Bells." The Byrne Brothers took the elements of this entertainment so often into vaudeville and out of it again into road shows that it is difficult to remember where it originated. ”
