Harrison spent most of 1974, it seems, working on Splinter's album. Then, he rushed out Dark Horse (recorded when he was "hoarse" himself) in time for the big American tour for the end of that year. It's so odd because doing any kind of tour is a very non-George kind of thing to do. Then, doing huge American shows in hockey rinks to 20,000 a night is the most un-George thing ever. Yet he did it. With Material World having been another smash hit the year before, and with Ringo's "Photograph" having hit #1 in the US, etc., George would not appear to have been in need of cash-flow. Having followed The Beatles' various stories and histories for decades now, I have never seen any adequate explanation for why George decided to tour in 1974. In short, why'd he do the most high-profile, energy-sapping kind of tour imaginable? I can speculate on a few things that may have been factors (none of which really satisfies me, however): - Bob Dylan had returned to live performance in early '74, and so it was in the air for sixties' icons to do big 70s'-style tours - Pattie having left him, George needed something big to boost up his own ego (?) - Ravi Shankar pushed him a bit (as he had with the Bangladesh project) -- perhaps with a slightly ulterior motive But looking back on it, it still seems a bizarre decision for George to have made.
