"Hold On, I'm Comin" was the first song where the higher voiced Sam Moore took over sole lead vocals on the first verse and the deeper, rougher voiced Dave Prater given the "response" role and second verse (at Hayes and Porter's suggestion)and the duo stayed with this winning formula on most of their future songs. The song was created when Hayes was trying to write and called to Porter, who was in the bathroom. Porter responded with "Hold on,I'm Comin" and a major hit song was born. "Hold On, I'm Comin", when originally released, received objections from radio station and Atlantic Record officials over the potentially sexually suggestive title, resulting in a quick re-write and name change, with the official U.S. Stax single released finally as "Hold On, I'm-A-Comin". Rolling Stone magazine named "Hold On, I'm Comin" one of the best 100 songs of the past 25 years in 1988, the song was the #1 song of the year for 1966 on the Billboard R & B charts. "Hold On, I'm Comin" received an RIAA Gold Record award for 1 million units sold in 1995, 29 years after its release. The LP "Hold On, Im Comin'" was ranked the #16 Billboard R & B album of 1966 and achieved a peak position at #45 on the Billboard Pop album charts. - from Wikipedia
