I promised superfan1 I'd post this. The cover, which did catch my eye:
Aaaaand, here's the context. Or the setup, anyway. The plot could pretty much be any characters, and it's... well it's Bob Haney. Really long, all over the place story. Ghost of John and Martha, Superman stands in as newsman for Clark, Batman visits a geek show, etc., etc. Lots of it revolving around 'New Metropolis'. Anybody know if it ever showed up in another story?
Clark's 'freed the slaves' comment/joke about salary what? Bruce's: 'siphon off excess population' what? Also: Ever hear of urban sprawl, 1976 World's Finest Comic?
Clothes. In a pool. Look like 'a guy struggling to swim'. Okay.

A whole bunch of other stuff happens, but I think Bruce and Clark on a date
