All at Once (Whitney Houston song)

"All at Once" is a song by American singer Whitney Houston from her self-titled debut album. The song was written by Michael Masser and Jeffrey Osborne and produced by Masser.

It is a ballad about a love who leaves without warning and the heartbreak that is felt afterwards.

"All at Once" was released in March 1985 by Arista Records as a single in several European countries, as well as in Japan in 1985–1986.

In North America it was not released as a single but did receive steady radio airplay on pop and R&B stations there throughout 1986.

The song became Houston's first significant hit in several European countries, including Belgium and the Netherlands, and also became her debuting hit in South Africa.

Following her 1987 performance of the song at the Sanremo Music Festival in Italy, Houston made history there as the first artist to give an encore performance of the same song at the festival.

The performance resulted in Houston having a top five hit of the ballad in Italy. It also became one of Houston's biggest hits in Japan, where it went gold.
