take it away
An invitation or instruction for someone to begin their performance. We've brought in a very talented young band to entertain you this evening. Take it away, girls! A: "For my audition, I will be singing a cover of 'Let it Be,' by The Beatles." B: "Wonderful. Take it away whenever you're ready."
Take it away!
Inf. Start up the performance!; Let the show begin! (Typically a public announcement of the beginning of a musical performance.) And now, here is the band playing "Song of Songs." Take it away! Sally will now sing us a song. Take it away, Sally!
