Singing for Pleasure

I am an English actor and singer on holiday in Adelaide for a few months (my visa runs until June). While I am here, I've been getting pangs for singing and performing, but naturally, most of the available opportunities are long term. Are there any choirs, singing groups, musical theatre groups, acting groups, open mic nights / poetry evenings I can be involved in whilst I'm here, without feeling as if I will let people down when I return to the UK? Please let me know if so - I am not looking to work per se, just to do what I really enjoy and meet some like minded people while I'm over here! My vocal style is unique, but I have a great deal of experience in all kinds of singing, especially lead and harmony (backing singing). I compose my own songs, which I feel gives me further musicality; you can hear some of these compositions on my website www.myspace.com/lizarcanemusic. Similarly, if there are any producers out there looking for a summer project / who need a musician to complete a course, I could be the one for you as I am eager to do a new, swift acoustic guitar / piano recording. Thank you! Liz Arcane
