The two versions of the Prophecy

Okay, here's my question about this overheard prophecy and it's probably an unfair question to ask, but...

If Snape only heard half of the prophecy and wasn't thrown out of the inn before the end of the prophecy, why doesn't Voldemort get himself a pensieve, extract the memory from Snape and go look for himself?  After all, Harry hears things in Snape's worst memory that Snape presumably didn't, such as the exchange revealing Lupin as a werewolf.
