The Capital Late Show With Marvin Humes 10pm - 1am
JLS made it through to the finals of last year's X Factor, but despite being beaten on the show by Alexandra Burke, their career hasn't stopped there.
In fact, X Factor has given Aston, Marvin, JB and Oritse a huge fan base, even before they released their first single.
So, with the backing of their fans, it's not surprising that when 'Beat Again' was released on Sunday, it went straight to the top of the Big Top 40 chart.
Fans, not content with the No. 1 are now launching a campaign to get the B-side to No. 2. The track, a cover of Rihanna's 'Umbrella' which they performed at Capital's Summertime Ball, has been slowly climbing the chart since it's release on Sunday morning but the fans are hoping to get it in to the top ten or perhaps even No. 2 on Sunday's show.
Find out what happens this week - The Big Top 40 Show with Rich & Kat - from 4-7pm on Sunday.
