I have been searching for this footage for a long time. I'm so glad to have finally found it. I love it. Mahalia could sing any song and make it sound soulful and heavenly.
That was a pivotal decade: America had a dramatic cultural shift. Thank God for Mahalia. She had a severe heart attack in that year in the summer and it was the beginning of her health struggles. That happened about 2 months or 3 before this was televised. She ended up losing about a hundred pounds by 1967 in the Spring.
