Take a key song used in the ceremony and bring it back (in a different version) for the reception to reinforce your theme.
For Example: “Without you” (Piano Guys version) for a ceremony processional song and the David Guetta version for the very last song of the night. Or “I’m gonna be (500 Miles)” (Sleeping at Last version) for a ceremony processional and the Proclaimers version for the last song of the night.
