Pushkin, Kukushkin...

Since I don't have television, I learn about important things from my Grandma. Today, she announced that Esenin just died in Moscow and that they were to bury him at the Novodevichy cemetery. Sure enough Grandma knew that Esenin had died in St. Petersburg about a century ago. But who was the poet she mixed him up with. Andrei Voznesensky! Was it the stature, or the misleading -esen- in both names?
