35; it was Adams' third single to chart in Europe. "Heaven" was the third single issued from Reckless. The record reached number 1 on the Billboard Hot 100 chart for two weeks in June 1985; the song previously peaked at number 9 on the Billboard Top Tracks chart from the A Night in Heaven soundtrack album in February 1984. "Heaven" has appeared on all of Adams' compilation albums with the exception of The Best of Me. The single was certified Gold in Canada in late 1985. Upon the release of Reckless in November 1984, "Summer of '69" received some airplay on album-oriented rock radio stations, but was mostly overshadowed by the tracks "Run to You" and "It's Only Love"; it managed only to reach number 40 on Billboard's Top Rock Tracks chart. After it was released as a single in June 1985, "Summer of '69" peaked at number 5 on the Billboard Hot 100. "Summer of '69" was issued as a single in Australia, Europe and New Zealand in 1985. "Heaven" reached the UK top 40, while "Summer of '69" peaked at 42.

Adams' previous singles had charted much weaker in Europe and "Summer of '69" would be Adams' second single to chart in mainland Europe. Although "Summer of '69" reached the top 10 in Norway and then the top 20 in the Austria, Ireland and Sweden, it was a moderate top 100 success in Germany, where it peaked at 62.

Released in September 1985, "One Night Love Affair" was the fifth and final single drawn from Reckless, peaking on the Billboard Hot 100 chart at number 13 and at number 7 on the Top Rock Tracks chart. "One Night Love Affair" had been officially released to Canadian radio stations in February 1985. The song reached the top 20 on the Canadian Singles Chart and remained there for another month.
