Brian May:
"Well, I don't think we thought success would be easy. When the record struggled to be heard, we just thought ... it'll take a bit more work until people understand what we have to offer. We were not offering normal "Pop" music of the time, so it was not going to be easy to turn the attention of Radio around. We believed!!! Also the whole hit record thing was not perceived by us as the only important thing , or indeed a thing of much importance at all. Our heroes were Led Zeppelin, after all, who NEVER had a hit single!! I think we wondered if having a hit would disqualify us from being taken seriously!

By some stroke of good fortune, we were able to have hits later, but still develop ourselves as an Album-Oriented touring band ..... we carved out our own destiny, by great persistence and much work, and some good tunes, I think! But I feel we were very fortunate too. "
