where can I find the PBS special- Laurena McKennat? Harpist?

Question

Highland Celtic singer/harpist.

Answer 1

Loreena McKennitt is actually Canadian. :-)

This page at PBS.org says that the program is not available for purchase.
http://www.pbs.org/wnet/gperf/shows/mckennitt/index.html
However, since that program was only done this year, it may be some months before it is released for sale. Best wishes, though.

Answer 2

Go to pbs.org You should be able to get the tape there.
