(The) Answer to SPOT the Blooper - Continuity error.

First, from the comments on the original post, some folks out there with really keen eyes!

Her slacks change colors? - Zack

The champagne is very bubbly when poured , but totally flat when they clink glasses ? - jerseygirlangie

He's got his cane in his left hand in the long shot and magically is holding the champagne glass in the next close shot. - RJ

He is originally holding the glass with the left palm facing to the viewer. At the clinking of the glasses, the viewer sees the back of his right hand now holding the glass. - Anonymous

 Here's the clip:

The Continuity error I noticed, the reason for the original posting on this, comes 26 - 29 seconds (+/- a second) into the clip.

As the champagne is being poured (at 26 seconds), Steed is holding his glass in his LEFT hand. In the next shot, fading-in from "black", as Anonymous noted, Steed is holding the glass in his RIGHT hand. And, he's wearing a glove, which he wasn't wearing in the previous shot. Mrs. Peele looks like she might be wearing a glove, or, her hand is deliberately unlit.

RJ's comment on the umbrella (or cane) is something I never would have noticed. There may be more. If you see one, leave a comment. Thanks.
