Well, Yes and no. If I remember correctly Larry and Lemmy met somewhere in May?? 1975. They where rehearsing and all that... On 13 July 1975 Larry recorded album with Pink Fairies "Live at the roundhouse". BUT On 20 July was first Motorhead show ever, their first working day in public. So, depends what you think is real start of Motorhead. Is it 20 July 1975 (For me it is) or it is somewhere in May? Pink Fairies released a single Between the Lines / Spilling for a fight on september 1976, IF I remember Larry was not in Motorhead anymore in this period. My point is, when he was playing in Motorhead Pink Fairies were paused from working.
