A brief mention of Hanson in a billboard article listing the many, many achievements of Michael Jackson:
Youngest act to top the Hot 100. When the Jackson 5’s “I Want You Back” reached the penthouse in January 1970, lead singer Michael was just shy of 11 and a half. Amazingly, this record still stands; only Hanson drummer Zac Hanson, a month past 11 and a half when “MMMBop” topped the chart in May 1997, has come close to beating Michael’s record. (Among solo acts, “Little” Stevie Wonder still holds the record, a chart-topper with “Fingertips” at age 12.)
