Welcome back to Karl Hyde, the singer/songwriter of the British band Underworld. The group became internationally known back in 1996, when their music was used in Danny Boyle's award-winning film 'Trainspotting'.

Today, Karl talks about one of his songs, Dark and Long from the band's strangely named album 'Dubnobasswithmyheadman'. A version of this song, along with the hit Born Slippy, are among the most memorable tracks from 'Trainspotting'. Find out here how the song was written and check out some vocabulary.

Karl Hyde reads the lyrics especially for us. Listen and see if you can fill in the gaps in the lyrics.

Karl, this song is long: it lasts 13 minutes on the album! And it has some dark imagery in it. But what is the story behind 'Dark and Long'?
'Dark and Long' was written over a long period of time. You know, things like 'Thunder thunder, lightning ahead' was... that was written in Minneapolis. And there are other things that were written in New York. And then there were later pieces written on the train to Romford [in the east of London]. 'Dark' - but 'dark' not in the sense of 'doomy' or 'down', but of just kind of a more mellow vibe that... You know, when you're out in the prairie lands of Minnesota and you see these thunderheads coming in, and the way the light changes and it kind of goes purple and yellow, and the sky becomes bruised... These are all very powerful images! But they're also to do with the sense of travelling, the sense of need to travel that for me, up until a very recent time, was crucial.
In the song, there's a whole verse about some waitress. What is it you find so special about her, Karl?
Waitresses are like mega-important - very very important. Waitresses and waiters, never give them a hard time. Because you never know what's gonna come back in your food! So these people are hugely important. But waitresses, they're like nurses. They're wonderful people, they're people that look after you and make sure you're happy, and put you right when you need a place to rest.
The line 'You was done up there mate' - what does it mean and where exactly does it come from? Probably not from America?!
Oh yeah, 'what a laugh - you was done up there mate!' It's like, you were... How can I say? Yeah, 'the wool pulled over your eyes', 'you were done badly by a deal there'. I live out in the east of London now and I'm fascinated by dialect and accent. I'm fascinated by English, you know, as spoken by other nations - and certainly as spoken by people in the east of London! It's fascinating, it's brilliant.
