October 1966 (and later?)
Ricky Maiocchi & the Trip   
People involved
Avid Andersen (bss); Ritchie Blackmore (gtr); Ian Broad (drm); Billy Gray (kbr?); Ricky Maiocchi (vcl).
Started a tour in Italy, but Blackmore & Co. left before it was finished. See, it started already then ;-) Maiocchi also cut some records during this time but it seems unlikely that Blackmore played on any of those.
