"Crimson and Clover" was released in late 1968 as a rough mix after a radio station leaked it. It spent 16 weeks on the U. S. charts, reaching number one in the United States (in February 1969) and other countries. The single has sold 5 million copies, making it Tommy James and the Shondells' best-selling song. (note: the RIAA did not award a gold record so the 5 million sales number is not officially acknowledged. ) It has been covered by many artists including Joan Jett and Prince.
