Guys,

What is Steve on about? that photo looks like the Steve we know and love
doesn't it?

Maybe it's just the touch of grey in the hair he is referring to?

What change? I don't feel any different...I'm still the same ol' Steve.

But something does seem a little askew in that picture you sent of me
Inge. Where in bejesus did you get that photo? (GRIN)

Thank you, Graham.
By the way, have you seen how Steve Gregory has changed slightly the
last time?
Just wondering if that is genetic or  what.
Maybe, I say again , maybe Steve will show a pic on himself. He writes
as usual, talks as usual, but...but...
Wait and see.
Inge
