Interim Grammy count: Four of four, one to go

We're now halfway through the awards ceremony, and thus far Robert Plant and Alison Krauss have stolen the show with their two televised awards. They also swept the two categories that were announced prior to the telecast, which were Best Country Collaboration With Vocals and Best Contemporary Folk/Americana Album.

And when the cameras started rolling inside the Staples Center, the awards continued to roll in. Plant and Krauss repeated last year's win in the Best Pop Collaboration with Vocals category, and then they picked up Record of the Year too.

And of course they'll perform by the time the winner is announced for the top prize, Album of the Year. They're supposed to perform a five-minute medley of "Rich Woman" and "Gone, Gone, Gone (Done Moved On)." "Rich Woman" is the Raising Sand track that earned them this year's victory in Best Pop Collaboration with Vocals, and the other song is what earned them last year's award.

Another track, "Please Read the Letter," is the one that earned Plant and Krauss their Record of the Year. It was the second single from Raising Sand.

Stay tuned for a final recap later!
