Input: Consider Input: Question: How many Grammy awards did the singer who re-recorded the song written by Sam Dees win? Passage:In 1983, The Manhattans released the album Forever by Your Side, by Columbia Records, which brought the two singles the group that year. The first was the song "Crazy", the great success of this album, peaked at number 4 on the R&B chart. The second single was the title track "Forever by Your Side", which had moderate success in the United States, peaked at number 30 on the R&B chart, but has become a great success and a romantic classic in Brazil two years later, when it was included as part of the soundtrack of a soap opera in the country in 1985. The success led to a Portuguese version the following year, called "Pra Sempre Vou Te Amar", which also was successful in Brazil, and has been recorded by several Brazilian artists. Another highlight of this album Forever by Your Side was the song "Just The Lonely Talking Again", written by the American singer and songwriter Sam Dees, which was originally recorded by The Manhattans this 1983 album and was later re-recorded by Whitney Houston on her second studio album "Whitney" in 1987.
