More 5G Than Man
If there's a better five song run in the history of recorded music, I'm not sure what it is, though I guess this one doesn't really count because everything after Walrus wasn't on the original EP.
But in terms of stuff that's been officially released, there just isn't a better stretch of listening material. You have the innovation/experimentation (Strawberry/Walrus), the nostalgic pop (Penny), the simple ditty that becomes a raucous rave-up (H-G), the idealistic sing along (Love)...each one of those is absolutely perfect.
Strawberry Fields Forever is my favorite song of all time, so it certainly has that going for it. It certainly might be my favorite stretch of music ever, not even counting Baby You're A Rich Man, which I've always had a soft spot for.
This discussion isn't all that off-topic, if you think about it. Friggin Cobbler hadn't heard Penny Lane, which is funny, and we found out about it on the internet.
