WATCH: Bob Bryan and his kids sing "Stand by Me"

Remember when Bob Bryan's daughter, Micaela, was so small she could fit inside a trophy?

Well she's now big enough—and her family is now numerous enough—that she can lead a family band on vocals and piano, with Bob on guitar and little brothers Bobby and Richie singing.

For the finale of Episode 3 of the ATP and WTA's online show, Tennis United, the group performed Ben E. King's "Stand by Me," reminding everyone that, no matter how separated they are from other people right now, they are never truly alone.

But that's not the only timely song Bob and Micaela have recorded. Here they are a couple of weeks ago playing a Bangles parody called "Pandemic Monday":

Meanwhile, Mike Bryan, a musician himself, might be able to have a band with his kids in a few years, as his partner, Nadia, is 40 weeks pregnant.

The twins announced in November that they'd retire at the 2020 US Open, but given the circumstances, nothing can be known for certain.
