This first appeared on Donna Summer's 1978 double album Live And More
, where it was part of a suite of songs bookended by her disco cover of "MacArthur Park
," #1 hit in November 1978 when it was released as a single. This version of "Heaven Knows" runs just 2:38 and segues seamlessly in the suite between "One Of A Kind" and the " MacArthur Park" reprise. The suite was the "more" part of the album, taking up an entire side (the other three sides were live cuts).
When "MacArthur Park" took off, it was obvious that "Heaven Knows" should be the next single. Casablanca released a longer version, running 3:37, as a single credited to "Donna Summer with Brooklyn Dreams," and also included it on the 1979 Brooklyn Dreams album Sleepless Nights
. It went to #4 in March 1979.
