According to the French Fan Club "Elvis My Happiness" the follow up to "ELV1S 30 #1 Hits" is scheduled for September 23, 2003. This compilation album will have the "new remastered sound" and would contain some songs that were hits in the USA/UK, and also tracks that were important in Elvis' career such as; "Viva Las Vegas", "Blue Suede Shoes" and "That's All Right Mama". This CD would also feature an unreleased second version of "Roustabout" written by Otis Blackwell and Winfield Scott.
There's also the possibility for a second remix and "Rubberneckin'" recorded during the Memphis 1969 Sessions (also used in the movie "Change Of Habit") would be the chosen track for this. More details when we have them.
