Often, toward the end of a song or instrumental break, (especially in the blues) a musician or band leader will call out, "Bring it home!" It's always seems to mean more than just "wrap it up" to me - it seems to beg just that much more soulfulness from the player.

Does anybody know where and when this phrase originated? Who was the first to use it (that we can find)? How has its meaning changed over the years?
