I've made a couple of replies to the Woodface doco threads about the 1970's Optigan instrument Neil Finn used on "Not the girl", "Chocolate Cake" and other Crowdies tracks(?), but thought it may be of general interst too.
Here's some useful links if you want to know more:

Hope this is of some use to someone out there.
