TWICE AS NICE
note from editor-at-large mr. jj: this chart 'record' comes with a LOT of provisos....
in the past, a double-sided single was usually listed 'side a / side b' ,
in the same chart position (unless the second side became a hit much later than the A side did).
i'm also pretty sure he's missing Donna Summer from his list
of acts that have succeeded themselves at number one. i *think*
she did it with 'Hot Stuff' and 'Bad Girls'.
