‘It was a moment of drunken inspiration, which we spend every second of our lives regretting.’ Via email, three-part harmony group The Segue Sisters collectively explain how their charming, sexy and witty brand of musical comedy came about.’We actually hate each other and have an in-group sexual history that rivals Fleetwood Mac. We’d rather not talk about it, basically. Pint?’ Intergroup liaisons and festering feuds aside, what can we expect from the Sisters’ first full hour Fringe show? ‘You can expect a very silly, fast-paced “comedycabaretmusicaltheatredance” show with songs spanning seven decades. There will be rubber ducks, beards and a leek.’

Since Edinburgh will be hoaching with comedic talent, will any special guests be dropping in? ‘There will definitely be some cameos, but not in the way that you would imagine. We’re not telling. You’ll just have to come along and have a look for yourself!’

And will the ladies be making tracks to this year’s festival on their quasi-eponymous mode of transportation? ‘YES! The kind people at the Segway Company have assured us that our trusty two-wheeled steeds will be waiting when we arrive in Edinburgh. If you’re very nice to us, we might let you have a go.’
