There are eight (well, more-or-less; apparantly Mrs. Russell knew a lot of songs, but, like my mother, wasn't a world champion at remembering the words) in The Wanton Seed: if you'd like them, send me a personal message with your e-mail address and I'll send them to you.  Slightly too many to post here in one go, though I'll do it if it seems sensible.   I've just picked up a copy of The Constant Lovers, too, which probably has some of her songs: not had time to look yet, but I'll try to tomorrow.
