Grammy-winning musician Ray Parker Jr. tells TODAY that he never gets tired of performing the “Ghostbusters” theme song that put him at the top of the charts in 1984, saying it’s like “holding a Lotto ticket.” He recalls composing the tune under pressure “in like 15 minutes.” Paul Feig, who directed the 2016 remake with Melissa McCarthy and Kristen Wiig, says the movie is out on Blu-ray with hours of extras.
