Playing steadily on the road throughout 1979 and 1980, Toast was Davy's backing band at the time. I found this photo of the group on eBay...
When Davy was on the road in 1979 and 1980, he was backed by a band called Toast. Alan Green (top left in the picture below), who later went on to work with Davy on his 1987 autobiography They Made a Monkee Out of Me, played keyboards in the group.
If you know the names of the rest of the members of Toast, please feel free to leave a comment or email me!
