Elvis On Tour was like Woodstock, projected 2.35 with the 1.85 sequences window boxed in the 2.35 frame, sometimes the single panal would open up to full 2.35, but it was all designed to be within the 2.35 frame.
They were shot 16mm with the idea of editing for multi screen and presenting in 2.35. If you read the book Dale Bell, the associate producer of Woodstock put together, he goes into detail, that on Woodstock they came up with special mattes for the single, double, and triple frames and those negatives were rephotographed in an optical camera with a Techniscope 2 perf pull down. Elvis On Tour, the single frame sometimes stretches to 2.35, sometimes it's, 1.85, and sometimes it goes to 1.37. That's just single panal. The blu rays of Woodstock and Elvis On Tour really show it, as the images are kept within the 2.35 frame.
