Euphoria

In an effort to capitalise on this new momentum, Def Leppard returned to its classic sound with the 1999 album Euphoria . The first single, ” Promises “, reunited the band with Mutt Lange and hit the US Mainstream Rock Track charts at No. 1 for three weeks although it did not receive much play on Top 40 radio; it was also a moderate hit in the UK and Canada. Euphoria peaked at No. 11 in both the UK and US, and at No 14 in Germany, although it was less successful in Canada and Australia.
