"Sincerely" is a popular song written by Harvey Fuqua and Alan Freed and first released by The Moonglows in 1954.
The Moonglows recorded the song during their first session for Chess Records, which took place in October, 1954 at Universal Recording Corporation in Chicago. The Moonglows' version reached number one on the Billboard R&B chart and number 20 on the Billboard Juke Box chart. Co-writing credits were shared by Moonglows band member Fuqua and disk jockey Freed. After it became known that Freed had inappropriately claimed songwriter credits for songs by bands he promoted (associated with his downfall in a payola investigation years later), Fuqua noted that Freed had in fact contributed to the songwriting for "Sincerely", thus his claim to a songwriting credit in this case was legitimate.
