"The irony about Berlin is that it was delivered as a concept album, but its component parts are from all over the place. The earliest songs off it are demos for the Velvet Underground. It's intriguing because 'Berlin' the song is from his first solo album, and then you've got 'Stephanie Says' [from VU] which has been changed to 'Caroline Says I'. He rejigged everything and came up with a concept album, but it's a hodge podge really. I interviewed him about Berlin and just about got away with it because I love the album. And I don't think it would have been as good if Bob Ezrin hadn't been producer. As much as David Bowie and Mick Ronson turned Transformer into the album it is, Bob Ezrin turned Berlin into the album that it is. The story goes that Bob Ezrin told his own kids that their mum had died just so he could record them crying for the album, and then when he had that on tape he told them, nah, she's alright really, I just made it up. That's what I heard anyway. You want to know why Lou Reed punched David Bowie that time? Well, I heard it was because Bowie offered to produce Berlin, but on the condition that Reed quit heroin. But Berlin is just an amazing album, especially coming straight off the back of Transformer, and you can tell that Lou Reed is not comfortable with being a pop star as presented by David Bowie. Somebody like Lou Reed [who] actually did reinvent the wheel – with some help from John Cale – with the Velvet Underground, and then one of his acolytes is seen to be helping him on his way. He was probably smarting a little bit from that. Really, Berlin shouldn't have worked, it was constructed from waifs and strays, but it has that great production with all the brass on it. 'Sad Song' is so beautiful. It's probably the most beautiful song you'll hear in your life."
