Dillie Keane at the Kings Theatre, Southsea

The outspoken singer has found a whole new generation of fans through social media and is hoping that her typical audience of ‘grandmothers and teens’ will pack out the Kings Theatre for a rare solo show without her fellow Fascinating Aida singers.

Dillie makes up one-third of the Olivier Award-nominated group, which is famous for its comedy cabaret songs.

Southsea-born Dillie is patron of the Kings and looks forward to gracing the stage for a ‘trawl through my rather more personal songs’.

She adds: ‘It’s certainly not ‘‘an audience with’’ – I’m not grand enough for that. It’s quite delicate actually, rather than our usual smut. Well, there’s a bit of smut – I couldn’t resist.’

Despite professing not to be a ‘West End Wendy’, Dillie and her band are well-known in the theatre world, with fans ranging from Helena Bonham Carter and Patti LuPone to Bette Midler, who has performed Fascinating Aida’s songs live.

Dillie says: ‘I wish she’d recorded them, because I’d get a lot more royalties. But a little bit of recognition is balm to the soul.’

One of the band’s best-known songs, Cheap Flights, was written in interesting circumstances, after flying out to attend the wedding of Dillie’s Macedonian housecleaner.

‘Afterwards, it inspired me to write the song - so myself and [writing partner] Adele got some rough Macedonian wine, sat in front of a café and wrote it.’

After uploading it to YouTube, the song became a viral hit, racking up 12 million views on the site.

‘I knew it would be,’ she says. ‘There were even versions with Russian and Hebrew subtitles.’
