A few good comments made up to now...
If you look at the 60s, you have to take into account the whole decade. My memory of 60/61 and 61/62 is vague at best. The 62/63 relegation season was obviously poor and was effectively (as the song says) the end for the sky blues.
63/64 and 64/65 were 'wilderness seasons' - City were becoming a solid 2nd division club with a few decent local lads playing, but seemingly destined for mid-table obscurity.
Joe and Malcolm arrived, and the world changed... 65/66 was probably my favourite ever season. The brilliant Johnny Crossan, winning the 2nd division title, a great cup run... Giddy at the possibility of actually going to a semi-final, only to be dashed by Everton after three games, and the arrival of the wonderful Summerbee and Bell.
66/67 was a season of change.. A few old favourtes moved on, some youngsters came to the fore, and we sat relatively comfortably (for then City) in mid-rable. The thing was,the general feeling 'on the terraces' was that there was more to come, and 67/68 (with the arrival of Franny Lee) proved us right.
Top-level English football was VERY different in the late 60s - The league was more balanced than nowadays; you could expect to see any one of 8 or 9 teams thinking, quite reasonably, that they may win the league. Games were more competetive, and every week we witnessed many of the greatest players that the English game has ever produced.
Take away the FA cup win, and it has to be said that 68-69 was a poor season for City - A season of erratic performances topped off with a cup win. 69-70 was much the same.
In hindsight, the 60s wasn't the 'wonderful' decade many of us City fans like to remember, but it was infinitely better than the 70s, 80s, 90s,and most of the 00s. Joe and Malcolm very nearly had the world of football at their feet, but didn't quite make it... In my opinion, Malcolm Allison's over-inflated ego and blind ambition destroyed what could have been - He stabbed Joe in the back and caused disruption in the Board room that escalated into farce over the next 20 years.
Let's face it - Football was better. I loved watching 'rollercoaster' City in the 60s, and I wouldn't change one second of it.
