Less than a week later it had launched five singles into the top 75 of the UK singles chart. Since then, according to the Official Charts Company, the American TV series has catapulted a staggering 42 tracks into the top 75 of the UK singles chart. And 17 into the top 40.
During its march on the charts the show has sold 1.8 million tracks, whilst all five Glee albums have gone top five - racking up 800,000 sales in the process.
