Yes, I laughed when I read "not a poor track on the record." George Harrison later said about M's Hammer "my God, what a fruity song."
There were a few other stinkers. Lennon's paean to Yoko was another one. Few "great" albums are overall perfect. I'm a big Beatles fan, but they had their share of awful songs.
George had some front considering he frequently squandered his 'two tracks per LP' with his annoying derivative Indian/raga noise.
