I'm never quite sure what was the last episode of Sooty and Co.

Was it the one which was about 50 minutes long (and had commercials
in the middle) where Sooty transports himself, Sweep and Matthew to
Lapland and they meet Santa (played by Brian Blessed) while back at
the shop Soo, Scampi and a human friend of Matthew's sell everything
in the shop just by hiring a boyband to play out the back.

Please can you tell me if this was the last episode of Sooty and Co
or whether there was another series of Sooty and Co.

Also which series of Sooty and Co was it that Richard and Liana
appeared in to help Matthew???

Talking about Richard Caddell and also on the Christmassy theme - if
you watch Sooty's Christmas Party (on My Bumper Sooty Christmas video
or The Sooty Christmas Video Show VHS) there is a very young Richard
Caddell with curly hair in this episode.
