I remember at a workshop at the end of October, she told us that she had had dry spells as far as writing songs.
She mentioned (during a song-writing class) even using a bra size to try to get a melody started! I said "you've got to be kidding", but she said she was perfectly serious.
I used to so look forward to her presence at Hava Nashira (and this past year, Shabbat Shira)
