Donovan probably had a hard time because too much was expected from him. There only ever was one Bob Dylan and there was only ever going to be one. Donovan had a plaintive voice, could play guitar and wrote some wistful songs. With intelligent producers, it made for good pop music at the time. I have heard different versions of both Colours and Catch the Wind. I am with Spaw on this one. Spot on. Catch the Wind is my favourite too.
