No, it isn't.

Most likely, you would say something like

"Sehr verehrtes Publikum, hereinspaziert ..."

(like an old-time circus or carnival announcer)

thanks for the replies.
i like the sound of both.
i have a follow up question, though

is #1 a standard/well-known phrase or something you just made up?

@3:

Well, AFAIK #1 is not a "well-known" or "standard" phrase ...

In particular, "alles und jeder" seems a little odd to me in this context.

thanks for that. the "alles" had been troubling me also.

i have now changed things around a bit to use the circus analagy and plumped for the hereinspaziert.
