A few weeks ago, a call arrived from the Langham hotel (formerly the Ritz-Carlton in Pasadena). It was the manager of a hip hop singer whose name, like that of all hip hop singers, was unfamiliar. He explained that his client felt a sore throat coming on and wanted a shot of cortisone. I receive those requests now and then; singers think it helps. Ear-nose-throat specialists theorize that cortisone’s anti-inflammatory action relieves hoarse vocal cords, but I’m skeptical, especially if it’s given just a few hours before the show. Cortisone takes at least a day to work. I quoted $250 which is my price for driving the twenty miles to the Langham, and he agreed. Those are delightful calls; I drive a long way, give a shot, collect money, and drive back. Sometimes hotel doctoring is easy. The manager added that the concert took place the following day, and he’d phone when the singer was ready.
