Ahead of his Aug. 15 San Antonio show — a performance being billed as his last in the city — balladeer Barry Manilow will award one local school and music teacher a $10,000 grant. The grant is a parting gift from singer-songwriter’s Last Concerts tour, a series of dates meant as a “final curtain call” for his time as a touring act. In an online statement, he said he’ll award a $10,000 grant to one school in each city on the tour through his nonprofit, the Manilow Music Project.
