I certainly continued to buy Shadows singles - as long as I knew they'd been released!
Saturday Dance - I bought this on a black label 45 in 1963 (I'd looked it up in the EMI catalogue).
Tomorrow's Cancelled - Bought this on release in the summer of 1967.
Goodnight Dick (HM) - Bought this on release, spring 1969, if I recall.
London's Not Too Far (HM) - Bought on release, mid-1967.
Love Deluxe - Autumn 1978? Bought straight away. The B-side was better.
Themes From Eastenders & Howards Way - I do have the vinyl. Probably bought it straightaway.
Shadowmix - I got the CD single by ordering it. Then later, the French version of "...At Their Very Best", which also included this track (21 in total).
