I'm guessing the "lost" cassette of songs may have been the so-called Fritz Demos...."Anybody Out There:", "See The World Go By", "I Need You", "Amber"....

.....those seem like more of something Stevie could have lost in storage, rather than "Secret Love".....SL seems like something she might have had out for awhile.

I could be totally wrong, per usual.
