How good they were. “Rock” is certainly a broad category so they’re a rock band...I just don’t think they’re as good as some people think. Not exceptionally good musicians, not exceptionally good singing voices, I think John and Paul actually wrote better songs after the band broke up, especially Lennon. I also wasn’t a big Wings fan...thought they were pretty soft and bubble gummy.Is your disagreement about how good they were or whether you consider them to be "rock?"
