Sirius repeated in a fuzzy sort of voice, but not because of any aftereffects of his spill and subsequent headbanging, but rather I would say from the immediate effects of Remus Lupin, although he did not quite realize that, and it wasn't exactly obvious to anyone, at least not yet.

And his face wore a look of supreme confidence in his ability to do so. "LET THE PARTY BEGIN!" he whooped optimistically, confident that Remus would not, could not and should not turn him down.
