If it hadn't been for The Dance's version of "Silver Springs," I would have never become a fan, but it is not that song that sucked me in...it's a long story... but the song that sucked me in for good was "Gypsy."
If you count their solo albums... I bought TISL and the Enchanted box set together. If you just do FM albums, it was TVBOFM.
My favorite version of "Rhiannon" is the live one off the 1980 "FM Live" album. Yeah, that version rocks my world...
