• This evolved out of a practice riff the band used to tune Jim Lea's violin before shows. According to Noddy Holder, it took just 20 minutes to write. They layered some chords over the distinctive riff, then ad-libbed some lyrics. When they played it to manager/producer Chas Chandler the following morning, he booked a studio immediately.
  
  Jim Lea recalled to Classic Rock magazine: "Our first hit, Get Down And Get With It,' was a cover. Chas kept ringing up saying we needed a follow up, fast. We'd started trying to write in pairs – Don [Powell] and I, Noddy and Dave [Hill] , but the other two weren't coming up with anything. Bolan was big at the time and all his songs were slinky and sexy. That seemed to be what it took to get a hit, so I had an idea to do something softer. At the time Nod and I used to jam along to ['30s French jazz violinist] Stéphane Grappelli and [Belgian jazz guitarist] Django Reinhardt, so I went over to his folks' house to work something up with him. I'd already got the structure and 20 minutes later we had 'Coz I Luv You.' It romped to #1. I had to turn round to Don and say, 'Look, we're going to have to keep this going.'"
• Originally written as a ballad, the band toughened the song up by adding handclaps and stamping sounds.
• The band's manager Chas Chandler encouraged Slade to write their own material. Noddy Holder says, "He told us to write a hit song, just like that, and that's not very easy to do. Jimmy and me wrote 'Coz I Luv You' in 20 minutes and Chaz was raving about it. We felt that it wasn't rocky enough for Slade so we added all the handclapping and boot-stomping, which made it much more commercial and became our trademark."
• The record's title was misspelt as "Coz I Luv You." Noddy Holder: "We thought 'Because I Love You' was a wet title for a song and so we used the spelling that would be on toilet walls in the Midlands and that made it more hard-hitting. When it went to #1, it gave us an enormous amount of confidence in our writing abilities. We had the courage of our convictions that we could keep on doing it." (above quotes from 1000 UK #1 Hits by Jon Kutner and Spencer Leigh)
• This was Slade's second chart entry in Britain and their first #1. Their first hit was a cover of a Little Richard song called "Get Down And Get With It," which peaked at #16 in the UK. >>

• This was the first of many Slade song titles that had unique spelling. Noddy Holder told Uncut: "We didn't like how the title would look on vinyl: 'Because I Love You.' It didn't fit Slade's image. In the studio, I had the lyric sheet written out phonetically in Black Country dialect which is how we used to write on bog walls. Chas Chandler, our manager, saw the lyric sheet, and said, 'Why don't we use that?' It caught on and had such an impact."
  
  "Of course, you got Prince doing it in the '80s, then all the hip-hop artists later on, so we started something. The education authorities got onto us for influencing the youth for bad spelling."
