Singer will now be playing 22 nights in total at the Eventim Apollo in London

Kate Bush has added a further seven shows to her residency at the Eventim Apollo, Hammersmith. She will now be playing 22 gigs in all.

The extra nights are 20, 23, 24, 26,27 and 30 September, and 1 October.

Tickets go on general sale on Friday 28 March, limited to four per person. Fans who registered with Bush's website were eligible to apply for a pre-sale allocation of tickets, all of which were sold within 30 minutes today.

Bush's surprise announcement of her return to live performance after 35 years – she toured only once, in 1979 – generated wild excitement last week. Her website crashed under the weight of visitors, and fans wondered online what form the shows might take. As the Guardian's Alexis Petridis wrote: "You can speculate wildly, but the truth is that no one really has any idea what Kate Bush is going to do, which seems perfectly fitting: that's been pretty much the case throughout her career."
