The whole complex that included the skating rink, the TR Suite and car park was within the ground area of the old stadium. Pretty much the only memory left is that one of the roads around there is called Charles Knott Gardens. Charlie Knott being the then owner of Southampton Speedway Club. He sold it all off to developers after Saints won the Championship. The speedway equivalent of the Premier League.
As well as the regular discos, I saw Hawkwind and The Clash at the Top Rank, but not on the same bill!
