OK, so turn off the laughing gas for a minute and rather than just saying the statement is funny and wrong, explain to me how it is wrong.
With statements like that, the laughing gas has been in circulation for a very long time.
In particular, how is Under Pressure (UK #1, US #29) not a bigger hit than some of the songs he did on S+V? Say, for example, TVC 15 (US #64, UK #33) or Be My Wife (missed the charts completely in both the UK and the US). In fact, I could go on and on with this list, but it's shorter to say that of the 32 songs Pegg lists as Sound & Vision regulars, only Space Oddity and Let's Dance did as well or better than UP in both the US and the UK, and only five others did better in the US than Under Pressure. So the other 25 songs on S+V did worse in both the US and the UK than Under Pressure did.
Furthermore, in addition to Be My Wife which never charted in either the US or the UK, a further eleven of the Sound And Vision regulars Pegg lists never charted in either the US or the UK, so by your own definition of hit, they were smaller hits than any of the songs he played on Outside that did, including the likes of Diamond Dogs, DJ, Boys Keep Swinging.
We've gone over this many times. Just because a song's chart peak is higher than another song's chart peak, doesn't mean it's sold more copies. In order to figure that out, it would be next to impossible. Oh and btw, I'd like to see the list of the "eleven songs" from the Sound & Vision tour setlist that weren't hits.
...don't tell god your plans...
