From Wikipedia, the free encyclopedia
"Vital Signs" is a song by progressive rock trio Rush from their album Moving Pictures. The song is heavily influenced by reggae styles. This influence would carry on into their next studio album, Signals. The song was released as the final single from the album. It has appeared in Rush's set lists as current as that of Rush in Rio. A live version of "Vital Signs" appears as the B-side on their "New World Man" single; besides the band's self-released 1973 single of "Not Fade Away/Can't Fight It," this is the only song Rush has ever released on a single that did not appear on a Rush album (Mercury #76179, US edition).
