I checked this out because I saw that John Barrowman was the guest star:
Watson & Oliver (BBC - Monday evenings) or here on iPlayer.
JB is absolutely hilarious - totally sending himself up - & the two girls (with all their various funny characters) are really good. It's a little bit hit & miss - as most sketch shows are - but there's definitely more hit than miss, for me. *g*
I'll be watching the next ep & hoping they can maintain the quality. :)
If you only want to see JB being completely awesome *g* then check out time stamps 14:50 & 24:04 (song).
Just found this cute behind the scenes vid (on youtube) of JB filming his guest spot. :)
And here's the song on youtube - for anyone who can't view iPlayer.
