THE YARDBIRDS - 'Over Under Sideways Down'/'Jeff's Boogie' (Columbia DB 7928) May 1966
The Yardbirds hit the top 10 once again with the self penned 'Over Under Sideways Down' which is a bit of a throwback to their earlier R&B movers but of course the Jeff Beck raga tinged guitar sound makes it very much a '66 swinger.
The flip 'Jeff's Boogie' is indeed another blues instro shuffler and somewhat of a calming influence after the psych beat of the other side.
Soon after the release of this 45 original bass player Paul Samwell-Smith left The Yardbirds to concentrate on production and was very successful of course with the early records by Cat Stevens. He was replaced by long time friend of the band Jimmy Page initially on bass guitar but soon after switched with Chris Dreja enabling him to become the second lead guitarist alonside Jeff Beck.
