Info on the Spotlite (as given above) contradicts the actual announcer heard on the LP. He gives Blakey on the date with Eldridge and Kay on the date with McGhee.

Didn't listen, but the info in the write-up is consistent with the announcer on the LP: in the group w/Eldridge, you get Blakey, w/McGhee, you get Kay (or, according to the Silver site, Blakey, but then the announcer would have been drunk or blind or whatever).
