In late 2001, Mick Jagger released his fourth solo album, "Goddess in the Doorway". It met with mixed reviews, reaching No. 44 in the UK and No. 39 in the US. A month after the September 11 attacks, Jagger, Richards and a backing band took part in The Concert for New York City, performing "Salt of the Earth" and "Miss You". In 2002, the Stones released "Forty Licks", a greatest hits double album, to mark forty years as a band. The collection contained four new songs recorded with the core band of Jagger, Richards, Watts, Wood, Leavell and Jones. The album has sold more than 7 million copies worldwide. It reached No. 2 in both the US and UK. The same year, "Q" magazine named the Rolling Stones one of the 50 Bands To See Before You Die, and the 2002–2003 Licks Tour gave people that chance. It included shows in small theatres. The Stones headlined the Molson Canadian Rocks for Toronto concert in Toronto, Canada, to help the city—which they had used for rehearsals since the Voodoo Lounge tour—recover from the 2003 SARS epidemic. An estimated 490,000 people attended the concert.
