Apologies, the full title of the new trio is The Omega 3

The new bass player is Da'aboth.

From the organ grinders themselves:

Back in the 70s and 80s a band called Roaring Jelly worked their socks off,
on the folk scene and beyond, proving you could make a living specialising
in utterly bizarre songs (and long sentences). The Guinness Who's Who of
Folk Music described them as "pioneers of alternative comedy before the term
became fashionable." Twenty years on - reupholstered, revitalised, fortified
with vitamins and fish oils and now calling themselves The Omega 3 - they're
back with a new bag of quirky, genre-busting songs plus some old favourites,
in a fresh bid to seduce the world with ridiculousness.

The Omega 3 are: Derek Pearce (vocal/mandolin/guitar/fiddle/banjo), Clive
Harvey (vocal/guitar/ukulele/banjulele) and Da'aboth (vocal/fretless bass
guitar).
