After the video some quotes from the band, explaining the song a little deeper.
'Sweet Child O' Mine' is a true song about my girlfriend at this time. (...) It's the first positive love song I've ever written. I never had anyone to write anything that positive about Geffen Press Kit, 1987
"If we did any kind of ballads, it was bluesy. This was an uptempo ballad. That's one of the gayest things you can write. But at the same time, it's a great song - I'm not knocking it - but at the time, it just did not fit in with the rest of our, sot of, schtick. And, of course, it would be the biggest hit we ever had." - Slash
"The 'blue sky' line actually was one of my first childhood memories - looking at the blue sky and wishing I could disappear in it because it was so beautiful." - Axl Rose

Slash: "I came up with that. Yeah, and then Izzy came in with the chord changes behind it or the chords that back it up, and then Axl started singing. It was just one of the songs – it’s really not that complicated when you listen to it as far as structure goes, but it just sort of evolved until it was finished. And then we went into rehearsals as a sort of pre-pre-production type of thing and just wrote the whole thing out, and I got the solo, you know - and, just like, that was the first solo I felt comfortable with, so I just did that – and it just evolved into something. It was real spontaneous, like most of the material on the record is real spontaneous. Guns N' Roses Interview Disc, June 1988
