Edwards (right) was one of two classically-trained cellists in the band
Former ELO drummer Bev Bevan says Mike Edwards's extrovert personality made him very popular during his time with the band.
Edwards, cellist with the Birmingham rock group in the early 1970s, died on 3 September when a bale of hay crushed his van while he was driving in Devon.
"He was a chubby little chap with a big black beard and the most amazing grin," said Bevan, who now presents on BBC WM.
"He became a bit of an extrovert and very popular with the Americans."
ELO sold over 50 million albums worldwide and had 20 UK Top 20 singles in a career spanning nearly 40 years.
Edwards, who was 62, joined the group in 1972 and found being in a rock band a bit of culture shock.
"It was hard to find cellists to play in a rock and roll band because they had to be classically trained," Bevan said.
"They immediately went on long American tours with us and it was a startling change of lifestyle playing cello in a classical orchestra and playing in a rock and roll band."
Bevan added that Edwards soon began to express himself on stage.
"He used to play 'Air on a G string' using an orange instead of a bow."
