the band's track "london underground", along with its accompanying flash animation, was a popular internet fad in the uk in 2005. it was set to the tune of "going underground" by the jam criticising the london underground strike that was on at the time. it contains very strong language. it was released with their first album, and a newly recorded version with a rock music accompaniment was included in "unfit to practise", as well as released as a single on the itunes store, reaching number one in their 'comedy' chart having been downloaded over 4 million times. in recent live performances, as well as the newly recorded 'rock' version, the line "...chewing gum on every seat" has been replaced with "... nail bombs on every seat".
