A cappella This incredible original spiritual takes hold of you in the first measure and doesn't let go until the last!  "No need to knock, no need to knock, the door is open, just come on in."  Once the basic rhythmic pulse is established, the rest is pure delight as the voice parts trade off in call-and-response style then build to a powerful finish.  This is one of those special pieces that your choir will want to perform again and again! Highly recommended!
