In the
60's, or thereabouts, there was a TV program, seen in
Toronto and
Ottawa, that used
signing to great purpose.
The neatest thing about it, was the poor theatre multimedia effect achieved when a story was told in words, acted, sung, pantomimed, and signed. No great sets were used, no elaborate costumes. Just the actors, their passion, and their technique. It was, ostensibly, a children's show, but, I think, reached a greater audience.
The theme music was from the Rolling Stones' album, Their Satanic Majesties Request. The main lyric, or title, "Why don't we sing this song all together, open our heads and the pictures come".
