In an interview with the Elvis Information Network website Kevan Budd shared a few details of the upcoming Follow That Dream SUN project. Apparently the set is now in its final stages of completion.
"A general overview of the FTD `Sun box set` is that it will include a good amount of unreleased material, including studio sessions (everything we have in the vaults), live recordings (newly restored) including amongst others, the unreleased Meridian, May 1955 performance where Bill goes crazy and Elvis is really rocking! Plus interviews, demos, radio ads and off course the odd surprise!
The book section is a massive project, including such items as the first known colour photo of Elvis in 1954 to unpublished Sun session tape notes and off course many, many more unseen goodies! The set is now in its final stages of completion"
