Well. I've not (yet) found any recordings using Vanguard Centre's organ.
I tried contacting them through the 'contact us' feature on their website, but without success. It keeps saying 'there was an error...try later.'
Being ever-so-hasty, I found an alternative email and just sent one to them, seeking their help to see if they can recommend a recording or two where I can hear their Pipe Organ being sounded.
Meanwhile, the search will continue.
Pipe Organ's have been a particular pleasure of mine since over 7 decades ago, and it could be said played a part in my love for instrumental music, especially the classics.
(Though unfortunately, Bach, though he played on magnificent instruments well worth the hearing, still delivers 'music' sounding to me more like warm-up exercises. But that's just an old Ent's opinion, I fear.)
