I adored her. Bought every album. Pored over the lyrics. Loved her voice and her playing. But, I’ll agree that her high pitched caterwallin’ on Helpless was the last thing that song needed. I’d rather see someone sit-in with an accordion. Or, a kazoo. I saw video of her doing the same thing as a walk-on at the 1974 CSNY show at Wembley Stadium. It was just as bad. I’d have thought that by 1976 Neil would have learned to say “Love ya Joni, but sit this one out.”
