to be colorful

Just watched Bee Gees' video regarding their whole life till now, and realized so many good songs are originally from them. For example, "how deep is your love", "how can you mend a broken heart". The most impressive part of their story was their bonding between families, especially the brotherhood. They are three brothers becoming the Bee Gees. They sang from their childhood till they were getting old. Even with the breaking apart or togetherness again, they still love each other and created more and more good songs. I admitted that I didn't know them till this video tape. However, I was impressed by their good work- their music which impacted the western music profoundly.
