it's but it's part & parcel of life =(
I like the way SHINPEI wrote/reflected about Kako Kubota's death in his blog entry today . Even though this has happened , SHINPEI wrote in such a way that he says it's not goodbye but rather it's the case of seeing you later as saying goodbye means that you will not see this person again
I checked their albums earlier on & I did saw Kako's name being credited in the CD sleeves of their 1st album
