Team Saade- over in stockholm have a task of updating the winnng song 'Popular' performance for Dusseldorf 2011. Some of Eric's dancers may need to be changed, and required to add backing vocal to the track, as also only backing vocal tracks are allowed in Eurovision. This is normal as at Eurovision, also only 6 people are allowed on stage for the performance at one time.
The other problem is that breaking glass effect may well not be able to be used for the track in Dusseldorf. In Melodifestivalen Eric performed last in his semi-final & at Globen for that reason - that any broken glass could be cleared away once all acts had performed.
It has been suggested that Eric Saade bring back his shower water effect of 'Manboy' in 2010.
I think this was alot better effect than the smashing glass, and as with Eurovision very often if you don't use a performance effect at the time..before too long someone else will! Plus Eric does that wet t-shirt look so well.
Note- it has now been confirmed Eric will use his original breaking Glass effect for Dusseldorf - hurrah
