I bought Brian Protheroe's album Pinball in the Notting Hill Record and Tape Exchange in the 1970s... and loved it. He's recently had a revival of interest and so tracks with accompanying video have been appearing on youtube.
There's the title track from that album Pinball, and others like Fly Now from the Pinball album too.
Although I didn't come across before youtube featured it, CitySong.
I know it's the kiss of death for an artist if I say I like them... but I like Brian Protheroe. His songs are great to sing along with, and to listen in the early hours of the morning.
