World Seems Difficult" was a top twenty hit, but polished up for the overseas market, sounded unlike anything the band had previously released. Two further singles, "Baby You're Wild" and "Overwhelmed" did not peak into the top 50, and promotion of the album was hindered after Smith injured his arm in a horse riding accident, and was hospitalised, which forced tour concerts to be postponed or cancelled. By early 1990, Mental As Anything members agreed to take a sabbatical to work on solo work and side projects. Then Deputy Prime Minister, Paul Keating, opened their second group studio art exhibition in 1990. 1990-1993: Side projects and sabbatical In 1986 Plaza released a solo single, a cover of the 1960s Unit 4 + 2 song "Concrete and Clay", which was a No. 2 hit; the subsequent solo album, Plaza Suite, also charted.
