LONDON — Rock legends The Faces are to re-form, with Simply Red singer Mick Hucknall filling Rod Stewart's frontman role, band members said on Thursday. The revamped 1970s group will play a gig at Goodwood, West Sussex, in August, followed by a tour in January, with a former Sex Pistol and ex-Guns N' Roses guitarist Slash helping out, alongside drummer Kenney Jones. Hucknall has been rehearsing with the band and the group say they cannot wait around for Stewart. "He just had the electricity in his voice like no time had gone by," guitarist Ronnie Wood said of Hucknall. "We haven't ruled Rod out. It's just that his schedule is so busy and his manager is just putting work in every time we try and work including Rod," he told BBC television. "We haven't got time to wait around for that. The music is hot and Mick Hucknall is singing hot so we're ready to go. The time is ripe." The band played a one-off gig last year at the Royal Albert Hall in London with various singers filling in for Stewart, including Hucknall. The band had been rehearsing with Hucknall, who will call time on his chart-topping soul band Simply Red after 25 years following a farewell tour this year. "He's normally a romantic, ballady-type singer but when he rocks, if you close your eyes, it's just like the Faces were in the 1970s, he can really sing them songs," said Wood. Their first gig will be on August 13 at the Vintage at Goodwood festival, an "annual music and fashion-led celebration of creative British cool". Former Sex Pistols star Glen Matlock will fill in for the late Ronnie Lane on bass guitar, while Slash will help out where possible. Wood said former Oasis guitarist Noel Gallagher, Stereophonics frontman Kelly Jones -- who has a gravelly voice like Stewart -- and Chris Robinson from The Black Crowes had offered to sing. The band evolved from the Small Faces when singer Steve Marriott left to form Humble Pie. Stewart and Wood from The Jeff Beck Group teamed up with Lane, Jones and keyboardist Ian McLagan to form the new outfit in 1969. After the Faces split in 1975, its members went on to their own successes. Jones later replaced Keith Moon in The Who; McLagan played with artists such as Bob Dylan; Wood joined The Rolling Stones; Lane formed his band Slim Chance, and Stewart became a chart-topping solo star.
