Echo Beach is fictitious (although I hear it is inspired by Sunnyside Beach), but they recently built a waterfront concert venue at Ontario Place named after it.
Pretty sure Echo Beach was by far their biggest (only) international hit. They also changed their name to M+M by the time BS/WS came out.
Not true.

The M+M years (1983 – 1986)[edit]
After the tour for This Is the Ice Age, Haas left the band over creative differences in a very public spat carried out in the "letters to the editor" column of Toronto's NOW. The band, now a quartet (Martha Johnson, Mark Gane, Jocelyne Lanois, and Nick Kent), signed to Canadian indie label Current Records, distributed by RCA.
1983's Danseparc was produced by Daniel Lanois, Gane, and Johnson. Gane, eager to drop the name "Martha and the Muffins", proposed that the group be now called "M + M". In a compromise, both names were used for a time, and the Danseparc album cover had both "M + M" and "Martha and the Muffins" printed on it.
The album's title track was another top 40 single in Canada and, for the Danseparc tour, the group was augmented by auxiliary players including guitarist Michael Brook. At the end of the tour, Gane and Johnson (now a couple) announced that, although they wanted to continue as a recording act, they also wanted to branch out in new directions by using new collaborators. In essence, Gane and Johnson decided that "M + M" was now Martha + Mark, along with studio musicians and sidemen.
The duo's 1984 album Mystery Walk was again co-produced by Daniel Lanois with Gane and Johnson, and it featured a large sticker crediting the band as "M + M o/k/a Martha and The Muffins". Guest players included drummer Yogi Horton, bassist Tinker Barfield, and the Brecker Brothers on horns.
Mystery Walk album gave M + M/Martha and the Muffins their biggest hit in years with "Black Stations/White Stations". The song was an anti-racist anthem whose first verse took radio stations to task for refusing to play a song about mixed-race romance, a story that Martha Johnson had heard related on the radio while driving in her car.
"Black Stations/White Stations" was a hit in Canada; in the United States, it reached No. 2 on the dance music charts,[1] but was ironically banned by many radio stations.[citation needed] "Cooling the Medium", the second single, was also a significant hit in Canada.
In 1985, Johnson and Gane started work on their next album in Montreal before heading to Bath, England to work with producer David Lord, resulting in the album The World is a Ball (1986). Although the lead single, "Song in My Head", garnered them some airplay (and was another top 40 hit in Canada), the album sold poorly, and Gane and Johnson subsequently moved to England for a time.
