I wonder, are they still friends? I thought Morrissey disliked her, and that he considered her to be a "cold" person, and so forth. (At least that's what he said in some interview from 97, I think.)
Anyway, som of the singles she recorded in the sixties were great! And yes, "Puppet on a string" is one of the best.

Morrissey and Sandie are currently recording together. They have been in close contact since September of 2000, when they spent time together for the first time in years. The song has a working title of "Who Knew" and will most likely NOT be included on the next Morrissey disc. Word has it that it may be used for an upcoming British film.
