OK I'll come clean here, I'm the director of music at St. Jude's so I know where the organs going but I can't say just yet!
However, I can say it is going on a west gallery at a church in London and going tonally unaltered.
The organ is a gem and will be sadly missed by us all at St. Jude's. The redevelopment of the building has been very long in the melting pot and we have been looking at all possible ways of using the organ either where it is in the building or re-using it in the new worship space. Unfortunately it is just too large both physically and tonally and we would rather it went somewhere else "unaltered" than to be selfishly carved up and "ruined" just to fit our new space. The new main entrance is going to be where the organ chamber currently is so it can't stay put!
As to the Aber organ we have that in store in Portsmouth waiting for further developments. At the moment the church are to start "phase one" in the Spring which means the Hill organ is probably going to be removed in May/June. The new organ can't be fitted until the end of "phase two" which maybe a few years away at present.
I was as horrified as some of seem to have been about it apearing on eBay especially as we had been trying to aquire the instrument since August 2006! The instrument will be ideally suited to St. Jude's, and is planned to go on a west gallery in the new worship space. I could tell you about the trials and tribulations of finally getting hold of it, but maybe in another post!
