Pena, who belted out Elvis tunes to lift the spirits of 32 other miners while they were trapped underground for 69 days, shot video with his cell phone and occasionally broke into song as he walked through rooms with displays of gold records, movie posters and Elvis outfits.
He also became emotional as he stood in a room where Elvis' piano still sits and learned that the last songs Elvis sang before he died were "Blue Eyes Crying in the Rain" and "Unchained Melody."
Pena's Graceland tour is part of a five-day visit to Memphis, which has included stops at Memphis Grizzlies practice and a stay at the luxurious Peabody Hotel.
On Sunday, Pena will visit Tupelo. Click here for link to our previous story.
