As a big Hawkwind fan for many years...I have to agree with the first part of your post - Lemmy was one of my main early bass influences.
from the multitude to follow, came some damn good bass lines - check out High Rise and PXR5 (from the PXR5 album), Freefall(25 years), hell, evern Harvey Bainbridge came up with one or two good ones.
I lost interest after the Xenon Codex, the whole style went way to self indulgent.
I must admit to not liking Alan Davey that much - way too far up his own arse for my liking - and just seemed like a poor mans Lemmy - and I am sure I read somewhere where he admitted the whole ricky thing was to be like lemmy.
During Alan's early period - The Chronicle Of The Black Sword was his crowning glory - I felt he never betterd what he delivered on that album (fantastic tour for that one)
I know there will be some who disagree with me, but from seeing them in the 70's, 80's and 90's, I have seen them with a few different line-ups, and Lemmy and Adrian Shaw stood out as the best of the bunch.
but none of them are as bad as the ex techie who took over - Mr Dibs - what a complete tit..poor sound, weak vocals, no stage persence at all and none of the memorable bass lines that had become synonymous with Hawkwind music over the decades.
70 to 80 was THE Hawkwind era - enough said.
