The death of Vicente Fernandez, the Mexican singer, may have had a cultural impact on par with the demise of Sinatra, but as Fernandez sang in Spanish, you could be forgiven for being only tangentially aware of him. I talk to three of his admirers, and recount the scene at the Ontario concert in 2012 where he kicked off his farewell tour, in my Wednesday column. The topic is a slight stretch for me, but I’m glad I wrote this and hope his fans forgive any fumbles on my part.
