Hi
Only recently discovered this thread and was reading through, agreeing with pretty much all you have been posting. Then I saw a couple of links which I recognised - because they are mine!

They are the two Twitter videos of Gleb and Mel on Valentines night, when he gave Mel the roses. Well .... I've finally got round to posting up the full video on Youtube, so would like to share with you all - it will make more sense now!
I started filming the now infamous 'crabbing' (very nice rear view version!) and kept on filming because Gleb grabbed the mic and kept on talking! Here it is in full .....

I agree with your observations - Gleb was great during this, but his wife was in the audience that evening and I remember he kept glancing over in her direction in a 'Is this OK?' kind of way.
I have another clip to share ..... I was very lucky to have great seats for the show, 3 rows from the front in the block right by the Judges, so I clocked a lot! Just as the show was beginning, a dancer came out in front of us and I saw Gleb appear from behind the curtain. Realising he was about to dance right in front of us, I managed to catch him cartwheeling in!

Think you can tell from this clip how great his interaction is with the crowd
Just to add - I'm a massive Strictly fan since Series One, but this was the first live show I went to. Thoroughly enjoyed it and felt so lucky being that close to the action and seeing everyone close up. Absolutely loved Mel, but then I always have. She made me smile sitting on the little chair (that Gleb got the rose from) during each dance, bopping along to the music

I'd love her to take over from Tess!! Sorry - I'm not a Tess fan .....
Also really enjoyed Helen and Alijaz dances. Helen and Anita were my favourites this past series, was gutted neither made the final. I really hope Gleb comes back to Strictly this year, looking at his tweets - get the feeling he would like to, it does sound hopeful. But I really loved Anita, their partnership worked so well on all levels - I do hope he gets an equally likeable partner next time.
Pretty gutted that Gleb is coming back to perform about 30 minutes away from me in a couple of weeks!! Those tickets sold out, but hopefully he will feel the UK love again and be back on Strictly or a UK tour of his own.
Hope you enjoy the videos - I was pretty chuffed when Gleb liked and re-tweeted it, so I ended up on his wall!
