Released as a single on 3 December 2001, "Words Are Not Enough" / "I Know Him So Well" charted at number five in the United Kingdom and number 21 in Ireland in December 2001 and was the group's last single to be released before their Boxing Day split later the same month. An animated music video was made for "Words Are Not Enough".
Chart performance
The single entered the charts at number five in the United Kingdom but fell out of the top 10 to number 14 the following week, making the song their last top-10 hit. It spent eleven weeks in total in the top 75 despite much lower sales than their previous singles. The sales of this single were only equaled by "Here and Now" / "You'll Be Sorry". It also peaked at number 21 in Ireland and was their last single to chart in that country.
Music video
The video for "Words Are Not Enough" is almost fully animated, apart from a brief appearance from the band at the beginning (filmed at Hedingham Castle in Essex), and didn't feature a dance routine much like the rest of their music videos did. The video begins with the real Claire being sucked into a magic mirror and the rest of the band following her. As they enter the magical world, they transform into computer-animated characters.
