Ok, so I'm here to help.
The album also sold 1,006 copies on vinyl before the official release.
The albums' US chart run with sales is as follows:
Week 1: #7 - 32,622.
Week 2: #30 - 9,618. (43,246)
Week 3: #53 - 5,946. (49,192)
Week 4: #106 - 3,902. (53,094)
Week 5: #83 - 5,187. (58,281)
Week 6: #151 - 3,135. (61,416)
Although the album exited the
Billboard 200 after 6 weeks, which isn't bad, it remained on the
Top Rock Albums chart for a further 6 weeks at least. Therefore I estimate that it sold around 80K when it left all charts and has now sold in the region of 100-150K. It's really hard to estimate but I think the tour ensured the album still sold relatively well so I would guess around 120K in the US by now.
I will answer the thread question. The album was NOT a flop. For a solo artist over 60 to debut in the Top 10 and sell this amount means that they are still incredibly popular and not just with the older generation. I could list hundreds of successful acts from the 60s/70s and 80s who can't sell a fraction of that these days but Stevie can still do it. Hope this answers the question!
