I Think We're Alone Now was covered by a singer named Tiffany in 1987 http://youtu.be/w6Q3mHyzn78 Doesn't compare to the original.
"But now old friends are acting strange,
they shake their heads, they say I've changed.
Something's lost but something's gained in living every day
....it's life's illusions I recall, I really don't know life at all. "
Joni Mitchell
