I'd liked Blondie since their first album and their brilliant early singles. But when this came along it was a step up and it gained them (and Debbie Harry especially) superstardom.
It's just a perfect slice of Moroderesque disco, and this is the full near-six minute version. What I've always loved about this record - and still love - is Clem Burke's brilliant drumming - especially on the extended outro. Quite simply superb.
Here's the music - enjoy!
