Only Mercedes Sosa can make me this happy listening to her album, huhmm, cd "Mercedes Sosa en Argentina," recorded in 1982 at the Buenos Aires Opera Theatre. Inserted in the front of the cd case is my ticket stub from attending her concert in 2002 at the Berklee Performance Center. Gracias a la vida!
I was in the third row with my friend Bhavana who thought that we were getting the tickets at half-price. "Thought" is the operative word.
