I don't think there is anybody on this forum qualified to speak on Ola's behalf ?
But if I'm permitted to voice an opinion ? Within the band there seems to be a measure of personnel rotation going on during this current tour. Bearing in mind that Ola has been touring and working non stop for four years now and taking into consideration that she has been struggling with her health for a while, a cold I think ? The type of thing that wouldn't bother you and I but if you are a hard working perfectionist as Ola is, can be more than a little tiring. Its her turn for a short break to get back into peak condition..........sorry, that makes her sound like some kind of race horse ! I'm sure you know what I mean though ? ;D
