Brock Holt sang the Halo theme song in the shower during a rain delay

The Red Sox are a musical bunch. They've been known to put on concerts in the dugout prior to games and Brock Holt has previously used the occasion of rain delays to break out the guitar and play some tunes in the clubhouse.
They found themselves in a rain delay Friday night against the White Sox, and Holt was feeling musical once more. This time, he took advantage of the acoustics in the shower to perform the Halo theme song for all to hear:

Based on the smile at the end, Holt seemed happy with his vocal performance. Or maybe he was just excited to enjoy that lollipop he was holding. Either way, it was definitely an eventful -- and musical -- rain delay in the Red Sox clubhouse.
