The Who By Numbers was released in 1975, eventually peaking at #7 on the UK album chart and #8 on the Billboard 200 (US). While “Squeeze Box” was a top 10 hit in the UK and Top 20 in the US, its follow-up, “Slip Kid” did not chart.
Nonetheless, a Rolling Stone review at the time stated, “They may have made their greatest album in the face of [their personal problems]. But only time will tell.”
The Who By Numbers was eventually certified Platinum (1M sales) in the US in 1993.
