While the front cover and labels have it as mono, the audio is actually stereo. For all intents and purposes, I'm listing it as a mono edition here since it even has a monaural catalogue number. On Stage was the first and only Elvis LP in Brazil to supposedly be released in both mono and stereo editions.
Recorded "On Stage" at the International Hotel, Las Vegas, Nevada.
