Found this on the inmuseworld.com forums
Jo Whiley just said that Muse were supposed to be in the Live Lounge this week but couldnt do it because one of the band members wive/girlfriends baby is overdue. Theyll be there next week apparently.
Im assuming it's Chris's wife... :)
Also, Muse will be on Zoe Ball's XFM Radio show next tuesday (4-6)
