Those albums for Albert Marx's Discovery/Trend labels shouldn't be forgotten about either - 'Lomelin', 'Jenna' and 'Calafia'. In terms of style, they bridge the gap between the 60s PJ stuff and the more recent releases. Many of the original lineup were still on-board at that stage too in the 'Orchestra of the 80s' (and the subsequent '90s' one, which I caught live).
That 90s band opened up with 'Viva Tirado' - unforgettable impact.
