• This David Bowie and Iggy Pop penned tune, commentating on the uselessness of much of modern communication, was the title song of the latter's 1986 album. It was one of eight songs co-written by Bowie and Pop on the record, which allmusic.com described as "the most calculatedly commercial album of Iggy's career."
• The word/phrase "Blah" or "blah-blah," meaning a representation of words that are too obvious or tedious to give in full, originated in the US during the early years of the 20th century. More recently the tripartite version has become more frequent as another way of saying "and so on." Ira and George Gershwin wrote a song called "Blah, Blah, Blah" for a film called Delicious in 1931 and in 2010 American singer-songwriter Kesha recorded a song with the same title on her debut album, Animal. The Police song "De Do Do Do, De Da Da Da" has a similar theme.
