It seems whenever anybody covers a Beatles song it's called a 'TRIBUTE' to the Fab Four....
however The Beatles lone Harrison-Lennon composition recorded in Germany, the (for them) rare instrumental was clearly by it's very name a Shadows style number - Paul even does a 'Jet Harris yell' during the piece ...yet I always see this number termed as just being a mere 'PARODY' of The Shadows ! - check wiki or many Beatles fans forums etc
which seems somewhat inaccurate indeed rather unfair - Tony Barrow's sleeve notes to the first 'Please Please Me' UK Parlophone LP by The Beatles quoted Brian Matthew in namechecking The Shadows ! (a quote also used by NEMS to promote 'From Me To You' single in 1963 as well)
and George once said; 'IF we can do as well as Cliff and The Shads...' in an early interview I recall
even Paul years later was doing a 'Hank Marvin' impersonation (very well, notably the grin, pointing his guitar about, and touching the centre of his specs while playing) in his 'Coming Up' promo film BUT by some (Americans mostly but some British writers too) is simply 'assumed' to be doing Buddy Holly - notably in some Beatles books or on Beatles forums !
several Beatles book writers have rather belittled both Cliff and The Shadows - it's worth noting who first featured the lead/rhythm/bass guitar and drums band format The Beatles used as a recording band
If everyone else can pay a 'TRIBUTE' to The Beatles...then why can't 'Cry For A Shadow' be accepted as The Beatles own 'TRIBUTE' to The Shadows...?
