9 days wonder

[Jedrek]

Hi, who knows what this expression means and what it originates from?
"9 days wonder" (or maybe "9 day's wonder" -- I'm not sure)

cheers!

"Nine days' wonder" to ktos lub cos co cieszy sie powodzeniem ale przez krotki czas. Na przyklad zespol rockowy, ktory ma tylko jeden przeboj, a potem sluch po nim ginie.

I did not expect this band to be just a nine days' wonder. Their songs seem very appealing.
