Van Der Graaf Generator bassist Nic Potter has died, aged 61.

The rocker passed away on Thursday (17Jan13) after suffering complications from pneumonia.

Van Der Graaf Generator frontman Peter Hammill announced the sad news on his website on Friday morning (18Jan13), writing, "I'm so sorry to have to announce that the great Nic Mozart (Potter) passed away last night. Deeply, deeply missed."

Potter joined the prog-rock band in 1969 when he was just 18 and left a year later.

He appeared on the albums The Least We Can Do Is Wave To Each Other and H to He, Who Am The Only One.

Potter returned to the band in the late 1970s.

The bassist also played on Hammill's solo albums and recorded sessions with guitar greats Jeff Beck and Chuck Berry, among others.
