1985 song by Whitney Houston
"All at Once" is a song by American singer Whitney Houston from her self-titled debut album. The song was released in March 1985 by Arista Records as a single in several European countries, as well as in Japan in 1985–1986. It was not released as a single in North America, but did receive steady radio airplay on Pop and R&B/soul stations there. It is a ballad about a love who leaves without warning and the heartbreak that is felt afterwards. It is written by Michael Masser and Jeffrey Osborne and produced by Masser.
