Double CD Anthology in 1986, with a few extra tracks including "Let's Get Serious" and "Let Me Tickle Your Fancy", though Motown somehow managed to credit Jackie's "Love Don't Want To Leave" to Jermaine - it was the first track on Jackie's one and only Motown LP. Most of the Anthologies were converted to CD in 1986, with extra tracks, and Michael J. got an Anthology of his own, but Martha & The Vandellas, The Marvelettes, and Jr. Walker missed out at that time, they wouldn't get 2CD sets until the early 90s, along with Mary Wells.
@Neil Forbes looking at the year of 1976 i was eight years out i was going to comment of Jemaine two 1980's hits of Lets Get Serious 1980 and Dynamite 1984.
Actually, "That's How Love Goes" was one of Jermaine's solo records too, and he contributed odd lines to some of the group hits, most obviously the bridge on "I'll Be There". Also, I just checked the track listing in Discogs, and there are actually six Michael solos, and one by Jackie Jackson, "Love Don't Want To Leave".
