my neighbour he is

Being a grandfather does not necessarily mean he is old, you can be a grandfather at about 24 years old now can't you. Butt as my fiance says "you're never too old for rock and roll"

Well I guess it depends on what sort of rock music, if this man is a grandfather then rock music started in his era, the 50's and the 60's was the start of it all, and ones tastes in this sort of music does not change, once you have been rocked you are rocked for ever...good on him a lot of people get to an age where they lose interest in everything and become grumpy, he is still out there....
