Throwing back to the week of August 24, 1963, we find a pre-teen Stevie Wonder (then billed as Little Stevie Wonder) atop the Billboard Hot 100 with ‘Fingertips – Pt 2,’ the B-side of the first single from his album The 12 Year Old Genius – Recorded Live.

The full ‘Fingertips’ is an instrumental jazz track that was split across two sides for release. It was the second half of the performance, when Wonder was called back onstage for an encore after a rousing bit of harmonica playing, that rocketed up the charts, giving Wonder his first #1 hit.

‘Fingertips – Pt 2’ spent three weeks at #1 and 12 weeks on the Hot 100 overall. That’s quite the feat for what amounts to a few minutes of improvisational jamming — not the sort of thing you expect to top the charts.

This single made Wonder the youngest artist to ever land a #1 on the Hot 100, a chart that was pretty young itself at the time. It’s a record Wonder has held on to in the 60 years since.
