"Another reason why "better tracks" sometimes get left off the original albums is because of the special guests that are already on the album. Flaming Pie has a great example with a "jam" track like "Really Love You". Paul got so nostalgic playing with Ringo again, he kept it on FP. The same thing happened with Tug of War. Paul got so excited of jamming with Stevie Wonder, he and George Martin kept "What's That Your Doing" on the album. "
Once again, this proves my point with Nigel Godrich. These jams would not have made the original album with him as the producer. These songs should have been "bonus" tracks or B side to a single. Even George Martin did not appear to be able to convince Paul to make better decisions about song selections or the quality of a song. It seems Godrich has been the only one able to be strong enough to tell Paul something is not good enough or the right song for the album and that is why CHAOS is basically flawless.
"Paul's Solo Albums (even the great ones imo) never became "legendary"like Revolver, Rubber Soul, Pepper, The White album and Abbey Road. Like you, I love Tug of War but there are great songs on it like Wanderlust that are not universally known. A great song like "Somebody Who Cares" is almost totally unknown. This did not happen to Paul's Beatle songs even the "non-singles"
First, beating a dead horse again I will say that part of the reason is he never played his solo music live with the exception of songs being on his current album enough to make them well known and maybe legendary. There have been rare exceptions like "Here Today" but we all know why that is being done every night. I believe music critics think some of his solo stuff is legendary but that will never happen with the general music public. There is too much surrounding the legend of the Beatles and everything he has done the last 50 years since will never be given a fair shake IMO. Oh well -lol.
