There are good ones, but I am perplexed as to why they did them. Was there record company pressure to be in on the biggest thing around? Were artists like Aretha or Otis lacking in material?
In general I don’t think they really work that well. Am sure Lennon amd Macca were thrilled, but hearing Otis Redding grunting his way through A Hard Day’s Night as an example is not really an improvement on the original.
