That Dandy Warhols song from a few years back. 'Bohemian Like You'. It was a really vicious and angry diatribe against slackerdom, that was used by BT to promote some new call facility they were promoting.
They'd already covered this subject area pretty adequately in 'Not if You Were the Last Junkie On Earth' - which had some great lyrics.
Is it just a rumour that 'Perfect Day' was a tribute to heroin addiction.
Nope, not a rumour. See also: 'There She Goes', 'Golden Brown', etc, etc.
Babybird's 'You're Gorgeous' is another one, of course - but I think that record's been spoken of more on OTF than almost any other in music history...
