Phoenix Boys Choir prepares to perform for NASCAR PHOENIX - The Phoenix Boys Choir is ecstatic to be back together again - and they have a big show coming up. The choir is going to be singing the national anthem for a NASCAR race, and they're doing so in an innovative, socially-distanced way. "We’re using radio frequency and microphones and transmitters to sing together synchronized, which we haven’t been able to do for a year now," said Herbert Washington, the artistic director for the Phoenix Boys Choir. And the results are treble-free as the kids take the fun up an octave.
