The Episode Guide gives a brief description of each A-Team episode and a list of actors / characters in that episode. So, if you're searching for, say, an A-Team episode with Boy George in it you should be able to find it by looking through the guide (the episode is "Cowboy George", by the way...).
     Use the following links to navigate through the five A-Team series.

Series 1:  Episodes 1 - 13 (23/1/83 - 10/5/84)

Series 2:  Episodes 14 - 36 (20/9/83 - 15/5/84)

Series 3:  Episodes 37 - 61 (18/9/84 - 14/5/85)

Series 4:  Episodes 62 - 84 (24/9/85 - 13/5/86)

Series 5:  Episodes 85 - 98 (26/9/86 - 8/3/87)

NOTE: Sorry, I haven't bothered linking to the series that I haven't started yet. Saves you going to a page, only to find that there's nothing there. I'll try and complete it as soon as possible. Thanks.
