Bumping this thread to update the list of records from the Hall label I'd personally love to hear the most, more than any other (some repeats from the previous list, though):
RH 34/35 (Just to hear whatever the voice impersonations on this one sound like!)
RH 46/47 (for the track "Laughter and Applause", which apparently has audio of somebody coaching the crowd on what sounds to make left in accidentally)
RH 56/67 (mainly for the track "Misc. Boings, Pops & Flutters (Forty)".)
RH 58/59
RH-76/77 (mainly for the track "Mixed Montage of Sounds & Music".)
RH 88/89, 90/91 and 92/93 ("Fun Effects" albums)
W 502/503 (for the crash sound effects on W-502)
W 508/509 (for the tracks "Old Cars for Comedy (Backfire) (6 Cuts)" and "Comedy Car")
In addition, any information on the currently MIA RH 82/83 and W-504/505 would be appreciated, as they're some of the only sound effect LPs they put out literally no info can be found on the Internet. No pressure on anyone here, but if anyone lurking about has them and would like to share, do lemme know.
