How old was Toni Basil when her single "Mickey" reached No. 1 on the "Billboard" Hot 100?

Antonia Christina Basilotta (born September 22, 1943), better known by her stage name Toni Basil, is an American singer, choreographer and dancer.

In 1982 she released the single "Mickey", which achieved international success. This song is a cover of "Kitty", a 1979 release by the UK band Racey, which was written by Nicky Chinn and Mike Chapman, with the latter also producing it. The original song did not include the famous "Oh Mickey, you're so fine" chant, which Basil added.

The video was conceived, directed, and choreographed by Basil herself for the UK-based label Radialchoice, before the inception of MTV in July 1981. Issued on Chrysalis Records in September 1982 in the US, the song knocked Lionel Richie from No. 1 on the "Billboard" Hot 100 in December. Basil was 39 years of age when it reached No. 1.

It also topped the chart in Canada where it was issued by Virgin Records. The single was quickly certified Gold and in early 1983 reached Platinum status for sales of over 2 million copies in the United States alone.
