Two key supporters of the San Antonio Philharmonic during its rise from the ashes of the now-defunct San Antonio Symphony have sued the orchestra, demanding it repay what court documents characterized as $180,000 in loans. The lawsuit, filed Tuesday in Bexar County District Court by married couple and major Philharmonic donors David Wood and Colette Holt accuses the organization of breach of contract. The petition seeks repayment of money the pair provided the Philharmonic to buy its music library and a band shell used in performances.
