group that repackaged traditional songs
in a sort of classic rock
"Repackaged" is perhaps an overly harsh term; Steeleye Span was musically very sound and their folk-rock sound is unique-sounding, though it does have a dated feel now. I really like it.
Plus, anybody that does a version of Thomas the Rhymer with an electric guitar gets a thumbs-up in my book. They're a very Bordertown-ish band, much like Shoolglenifty in that they blend the traditional and the modern.
Other than that blending, though, the two bands are almost nothing alike.
