The event will be headlined by Flash as Queen on Saturday night; and Charles Duke, with his band, as Elton John on Sunday.
Other festival highlights include Madonna by Vicky Cluskey, Lady Gaga by Maybe Gaga, and Juno Rising appearing as both Alanis Morissette and with an ’80s genre set.
There will also be Britpop favourites from The 45s, Rock Anthems from Majestix; and a set from Rock of the Pops/ The Ibiza Band who will be playing a 90s Club Anthems set, while Nevaeh will be belting out the hits in a Girl Power set.
Family fun will also be high on the billing with Music from The Movies, The Ogretones performing songs from The Shrek; and Snow Princess Parties making an appearance. Bouncy castles and inflatable slides will be sure to keep children entertained, too.
Emer said: “Working in the music and events industry is always exciting and I thought that the acts should come to us, to the New Forest.
“I’m also excited that my Lymington family and friends – who have been hugely supportive of Sham Rocks – will have the chance to see what I do.”
Emer added: “I see lots of festivals that are overwhelmed with costs, so it’s important to me that ticket prices are also affordable.”
The festival has partnered with Lymington’s Oakhaven Hospice to raise money through ticket sales and donations. Oakhaven community fundraiser Hannah Davies said: “Sham Rocks will be raising critical funds to help ensure the continued provision of Oakhaven’s outstanding and much-needed services.”
Attendees will also be able to enjoy a festival bar featuring a curated selection of craft beers, lagers, ciders, prosecco and premium spirits, as well as several local food stalls.
The GiG Bar is launching that weekend and in addition to creative industry networking, it will offer opportunities for emerging talent to develop their portfolio in the fields of; photography, journalism, radio broadcasting, performance, sound production and general festival experience.
Sham Rocks will run from noon to 8pm. Adult day tickets are priced £12, with weekend tickets available for £22. To book, visit www.ticketsource.co.uk/fireflyfestivals
