two Underground Ernie fundraising events were held at the railway which were hosted by The Karen Ingram Foundation With over £3,500 raised on the night at the first event, which raised money for the hospital which cared and looked after Karen Ingram, for whom the events were in memory of. Co creator John Deery also attended the special charity evening, along with his family. With Eastleigh no longer hosting events involving Days Out with Ernie, a final fundraiser was held at the railway in 2010, however this was not themed to Ernie, due to the railway no longer having the Ernie characters available to use. Theme song The show's theme song, performed by members of The Wonder Stuff under the name "HRB Music", is called "The Importance of Being Ernie". This is a reference to Oscar Wilde's play The Importance of Being Earnest (Ernie is short for Ernest). Future A second series has been on the cards since 2006. Co-creator John Deery has been seeking a £5.5 million investment in a bid to break the US market, with funds raised from that going towards making a second series. This hasn't happened yet, however. According to creative director Adam Batham, the strained relationship between 3D Films and Joella Productions prevented another series from being made.
